Hormone Replacement Therapy (HRT) refers to this balancing of hormones for optimal health and wellness. Human Growth Hormone (HGH) is a complex protein hormone of 191 amino acids that is produced in the anterior pituitary, a gland attached to the Hypothalamus, which is found at the base of the brain.
Testosterone is a hormone produced by the testicles and is responsible for the proper development of male sexual characteristics.
The only accurate way to detect the condition is to have our doctor to measure the amount of testosterone in your blood. Female hormone replacement therapy includes supplementing the body with either estrogen alone or estrogen and progesterone in combination during and after menopause.
Estrogen and progesterone together thicken the lining of the uterus, preparing it for the possible implantation of a fertilized egg.
Hormone therapy helps to replenish the estrogen, relieving some of the effects of menopause such as hot flashes, vaginal dryness, and other symptoms such as night sweat, and dry, itchy skin. Testosterone increases availability of carotenoids -- Androgens and carotenoids play a fundamental role in the expression of secondary sex traits in animals that communicate information on individual quality. Temperature and the timing of reproduction -- Many bird species reproduce earlier in years with high spring temperatures, but little is known about the causal effect of temperature. Variation among bird species in the relative amount of yolk in eggs and the amount of energy available to the developing embryo (kJ-g -1, or kilojoules per gram). Incubation temperature and avian sex ratios -- Although common in reptiles, incubation temperature has not been considered to be a factor in determining sex ratios in birds. Explosive eversion and functional morphology of the duck penis -- Coevolution of male and female genitalia in waterfowl has been hypothesized to occur through sexual conflict. This association between neurons and SSTs provides evidence that SSTs are innervated and suggests that the storage and release of sperm from SSTs can, perhaps, be controlled.
That sperm in the SSTs are invariably positioned with their heads directed towards the distal end of the tubule suggests that egress from the SSTs is passive. In contrast to most other taxa, where only a single sperm enters the ovum, polyspermy is typical in birds.
Relative egg mass (corrected for adult mass) is greater in species with longer embryonic periods (days) among 64 passerine species in tropical Venezuela, subtropical Argentina, and north temperate Arizona.
Avian mothers create different phenotypes by hormone deposition in their eggs -- In birds, mothers deposit substantial amounts of androgens in their eggs, and experimental evidence indicates that these maternal androgens influence the chick's early development.
The long-lasting effects may be mediated by an upregulation of androgen receptors later in life. Evolution of egg color and patterning in birds -- Avian eggs differ so much in their color and patterning from species to species that any attempt to account for this diversity might initially seem doomed to failure. Several species of birds have blue eggs, and David Lack (1958) suggested that, in habitats where light levels are low, blue eggs might be cryptic. This means the shot must penetrate the skin and subcutaneous tissue to enter the muscle itself. The common sites for intramuscular injections include the buttock, lateral side of the thigh, and the deltoid region of the arm.
The best site for steroid injections is in the gluteus medius muscle which is located in the upper outer quadrant of the buttock.
The upper outer quadrant is chosen because the muscle in this area is quite thick and has few nerves. Injecting here reduces the chance of injury to the sciatic nerve which runs through the lower and middle area of the buttock. If an injection is too close to this nerve or actually hits it, extreme pain and temporary paralysis can be felt in these areas. This is especially undesirable and warrants staying as far away from this area as possible.
Usually, intramuscular injections in the thigh are only indicated for infants and children. The vastus lateralis muscle is the only area of the thigh that should be injected intramuscularly. This site is determined by using the knee and the greater trochanter of the femur as landmarks. The greater trochanter is the bony area that you can feel where the femur joins the pelvic girdle. The mid portion of the muscle is located by measuring the handbreadth above the knee and the handbreadth below the greater trochanter. It is important to choose the proper syringe for the administration of injectable anabolic steroids. There are a number of steps that should be understood in order to complete a safe and proper intramuscular injection.
Then, take a brand new syringe out of its wrapper, remove its plastic top, draw about 2 ccs of air into it and insert it into the vial.
Inject this air into the vial; this creates pressure within the vial and makes it easier to draw out oil based preparations. By using two needles for every injection, you can take advantage of using the full sharpness of the pin. The needle does suffer some dulling when it is pushed through the firm rubber stopper on a vial.
Providing there is no blood present in the syringe, slowly press the stopper down until all the oil is injected. Then, quickly pull the needle out and take another alcohol swab and press firmly on the injection site.
It is important that the liquid is not injected too quickly as this causes more pain at the site during the injection and in the proceeding days. After this procedure has been completed, return the plastic caps to shield the needles and make sure they are discarded properly. To avoid discomfort and excessive scar tissue at the injection site, it is not wise to inject more than 2 ccs of solution per shot. It is also not prudent to use the same injection site more than twice a week (once a week is preferred). Hormone replacement of estrogen, testosterone and other hormones in women and men via creams, pellet therapy or other methods increases female and male libido, weight loss, muscle tone and decreases menopause, andropause and more. Like testosterone, estrogen, progesterone, melatonin or DHEA, HGH is one of many endocrine hormones that decline with age. Testosterone is also important for maintaining muscle bulk, adequate levels of red blood cells, bone density, sense of wellbeing, and sexual and reproductive function. This sometimes may take several measurements, since levels of testosterone tend to fluctuate throughout the day.
Estrogen also influences how the body uses calcium, important for strong bones, and helps maintain healthy levels of cholesterol in the blood. Lowered or fluctuating estrogen levels may cause menopause symptoms such as hot flashes, and medical conditions such as osteoporosis. As prebasic molt ensued, plasma levels of testosterone were basal and remained so throughout autumn and winter.
In birds, androgens regulate song, aggression, and a variety of sexual ornaments and displays, whereas carotenoids are responsible for the red, yellow, and orange colors of the integument. Temperature may have a direct effect on timing of reproduction, but the correlation may also be indirect, for instance via food phenology.
From top to bottom, the hatchlings are an altricial Brown Creeper, a semiprecocial Least Tern, a precocial Ruddy Duck, a superprecocial Mallee Fowl (Leipoa ocellata), and a Brown Kiwi (Apteryx australis).
However, Goth and Booth (2005) found that incubation temperature does affect sex ratios in megapodes, which are exceptional among birds because they use environmental heat sources for incubation. This hypothesis raises questions about the functional morphology of the waterfowl penis and the mechanics of copulation in waterfowl.


2001) -- Immunohistochemical staining of a turkey uterovaginal junction and sperm storage tubules. As a consequence of selection during their migration through the vagina, only 1–2% of inseminated sperm enter the SSTs, the rest are probably ejected the next time that the female defecates. Several sperm enter the germinal disc region, hydrolyzing the IPVL via the acrosome reaction of the sperm, whereby the release of enzymes from the sperm acrosome enables the sperm nucleus to enter the ovum. Open symbols reflect cavity-nesting species and show an interacting effect where their larger clutches are associated with relatively smaller eggs. Larger eggs are indeed associated with fewer eggs across taxa and can yield higher-quality offspring. Despite the well-known organizing role of sex steroids on brain and behavior, studies on avian maternal egg hormones almost exclusively focus on the chick phase. Since these hormones suppress early immune function of the chick and reduce long-term survival, mothers may be faced with a trade-off between producing offspring with lower survival prospects but higher reproductive success per year, or with higher chances of survival and lower annual reproductive output. Kilner (2006) reviewed the literature that, when combined with the results of some comparative analyses, suggests that just a few selective agents can explain much of the variation in egg appearance. Evidence now suggests that such spots are located where the eggshell is a bit thinner (likely due to a calcium deficiency in the diet of female birds), with the pigment serving to strengthen the shell (Gosler et al.
If true, that could help explain the blue eggs of some open-cup nesting birds that occur in forest habitats such as Wood Thrushes. The first sign of approaching egg- laying was usually intensified breathing, occasionally with rhythmic opening and closing of the bill that pointed either horizontally forwards or more or less upwards. The opening and closing of the bill and rhythmic movements of the back and tip of the tail occurs repeatedly for up to 4 minutes in the Prairie Warbler, presumably corresponding to the duration of egg- laying. Because of the large number of muscle fibers and extensive fascia, (fascia is a type of connective tissue that surrounds and separates muscles) the drug has a large surface area for absorption.
The significance of this decline is controversial and poorly understood, but typically does not result in erectile dysfunction (ED), though its replacement usually results in an increase in sexual desire.
When the ovaries no longer produce adequate amounts of these hormones (as in menopause), hormone replacement therapy can supplement these levels.
Parallel, but independent, research lines suggest that the evolutionary stability of each signaling system stems from tradeoffs with immune function: androgens can be immunosuppressive, and carotenoids diverted to coloration prevent their use as immunostimulants. As climate change has led to substantial shifts in timing, it is essential to understand this causal relationship to predict future impacts of climate change. In the Australian Brush-turkey (Alectura lathami), a mound-building megapode, more males hatch at low incubation temperatures and more females hatch at high temperatures, whereas the proportion is 1:1 at the average temperature found in natural mounds.
However, only a single spermatozoon fuses with the female pronucleus and the remaining sperm are shifted to the periphery of the germinal disc and play no further part in development. Tropical passerines appear to follow theory because they commonly exhibit slow life history strategies and produce larger, but fewer, eggs compared with northern species.
By producing eggs that differ in levels of maternal hormones, mothers seem to produce a variety of phenotypes, perhaps an adaptive strategy in unpredictable environmental conditions. However, Lack’s hypothesis cannot explain why some birds that nest in cavities, like European Starlings and Eastern Bluebirds, also have blue eggs. The head was drawn in and the body feathers were somewhat fluffed out; the Coal Tit in addition raised its crown feathers.
For 3 eggs of the Goldcrest, only 8-9 seconds elapsed between the first visible sign of pressure and the moment of egg- laying.
The 22 and 23 gauge needles are not so large that they are difficult to insert, yet are large enough for solutions to easily be propelled through them. Despite strong similarities in the patterns of sex, age and seasonal variation, social function, and proximate control, there has been little success at integrating potential links between the two signaling systems. Chicks from lower temperatures weigh less, which probably affects offspring survival, but are not smaller. The blue areas (se) are the surface epithelium lining the lumen of the uterovaginal junction and the epithelium of the sperm storage tubules.
An unknown but probably small proportion of sperm move directly to the infundibulum (the site of fertilization) without entering the SSTs, although these are likely to fertilize only a single ovum. Sperm accumulate or move relatively slowly through the infundibulum so that there is usually a population available to fertilize each ovum as it is ovulated. Fertilization includes the penetration of ovum by sperm as well as the fusion of the male and female pronuclei (syngamy).
Martin (2008) found that relative egg mass (corrected for adult mass) varies extensively in the tropics and subtropics for the same clutch size, and proposed a hypothesis to explain egg size variation both within the tropics and between latitudes: Relative egg mass increases in species with cooler egg temperatures and longer embryonic periods to offset associated increases in energetic requirements of embryos. Since natural selection acts upon such phenotypic variation, shaping a population's demography, the role of maternal androgens in this selective process may be much greater than anticipated until now.
Ancient diversification in nest location, and hence in the clutch's vulnerability to attack by predators, can explain basic differences between bird families in egg appearance.
The spots consist of protoporphyrin pigment that birds synthesize during production of the heme component of hemoglobin (Burley and Vadhera 1989) and integration of this pigment into the eggshell provides additional strength. One hypothesis is that the blue-green color of eggshells represents a signal of female quality to their mates ( Moreno and Osorno 2003). Egg size variation among tropical and temperate songbirds: an embryonic temperature hypothesis. Ideally, intramuscular injections should be given deep within the muscle and away from major nerves and blood vessels.
These parallel patterns led us to hypothesize that testosterone increases the bioavailability of circulating carotenoids. Megapodes possess heteromorphic sex chromosomes like other birds, which eliminates temperature-dependent sex determination, as described for reptiles, as the mechanism behind the skewed sex ratios at high and low temperatures. The arrow points to a magenta-stained area of one SST that indicates the presence of actin (a protein found in smooth muscle. On ovulation, the ovum is captured by the prehensile, funnel-shaped infundibulum and the sperm swarm over the surface of the ovum; their target is the germinal disc, which contains the female pronucleus. Because embryo development begins almost immediately, many cell divisions have occurred by the time the ovum has become incorporated into the egg and the egg is laid (in most species) 24 hr later.
Egg temperatures of birds are determined by parental incubation behavior and are often cooler among tropical passerines because of reduced parental attentiveness of eggs. The ancestral white egg has been retained by species whose nests are safe from attack by predators, while those that have moved to a more vulnerable nest site are now more likely to lay brown eggs, covered in speckles, just as Wallace hypothesized more than a century ago.
When a female bird has insufficient calcium to deposit in a shell, protoporphyrin molecules that have a semi-crystalline structure similar to that of eggshells are apparently deposited instead instead of calcium. The pigment responsible for the blue-green color is biliverdin, a substance produced when the hemoglobin of damaged red blood cells is catabolized and also known to have strong antioxidant properties.
Then the tip of the tail started nodding movements synchronously with rhythmic depressions of the rump.These movements which apparently were caused by throes of parturition when the egg traveled down the oviduct, were almost invisible to begin with but gathered in strength and ended with a sudden elevation of the rump that marked the moment of egg-laying.
The Cuckoo (Cuculus canorth) which is a brood parasite, is known to lay the egg remarkably swift, usually within 10 seconds with a lower limit of only 3-4 seconds. With Propionate, androgenic side effects seem somewhat less pronounced than with the other Testosterones, probably due to the fact that blood levels do not build up as high.
Clenbuterol is a selective beta-2 agonist that is used to stimulate the beta-receptors in fat and muscle tissue in the body.
Instead, Goth and Booth (2005) suggest a sex -biased temperature-sensitive embryo mortality because mortality was greater at the lower and higher temperatures, and minimal at the middle temperature where the sex ratio was 1:1. The collagen matrix of the penis is very thin and not arranged in an axial-orthogonal array, resulting in a penis that is flexible when erect. Cooler egg temperatures and longer embryonic periods explained the enigmatic variation in egg mass within and among regions, based on field studies in tropical Venezuela (36 species), subtropical Argentina (16 species), and north temperate Arizona (20 species). Antioxidants are important because they can convert free radicals, molecules that can damage DNA, proteins, and other macromolecules, into less reactive substances. Avian egg color and sexual selection: does eggshell pigmentation reflect female condition and genetic quality?


Clenbuterol exhibits most of its effects on the stimulation of both type 2 and 3 beta-receptors.
To test the hypothesis that female genital novelties make intromission difficult during forced copulations, Brennan et al.
The clustering of sperm and holes made by sperm in the IPVL around the germinal disc suggest that sperm might use chemical signals to locate the germinal disc.
It is possible that some species have subsequently turned these ancient adaptations to new functions, for example to signal female quality, to protect eggs from damaging solar radiation, or to add structural strength to shells when calcium is in short supply.
Deposition of this pigment in eggshells by laying females may, therefore, signal their capacity to produce antioxidants and control free radicals. Testosterone treatment increased the concentration of carotenoids in plasma and liver by >20%.
Because the relevant temperature period started three weeks prior to the mean laying date, with a range of just 4°C between the warm and the cold treatments, and because the birds were fed ad libitum, it is likely that temperature acted as a cue rather than lifting an energetic constraint on the onset of egg production. Thus, large egg sizes may reflect compensation for increased energetic requirements of cool egg temperatures and long embryonic periods that result from reduced parental attentiveness in tropical birds. The threat of predation, together with the use of varying nest sites, appears to have increased the diversity of egg coloring seen among species within families, and among clutches within species. Male birds paired to females of such quality that they are able to deposit antioxidants in eggshells rather than retaining them may then expend greater effort in caring for their superior offspring (Kilner 2006).
Evidence for the innervation of sperm storage tubules in the oviduct of the turkey (Meleagris gallopavo). Plasma carotenoids were in turn responsible for individual differences in coloration and immune response. Eversion occurred successfully in a straight tube and a counterclockwise spiral tube that matched the chirality of the waterfowl penis, but eversion was significantly less successful into glass tubes with a clockwise spiral or a 135° bend, which mimicked female vaginal geometry. Brood parasites and their hosts have probably secondarily influenced the diversity of egg appearance.
In support of this hypothesis, the provisioning rates of male Pied Flycatchers (Ficedula hypoleuca) and the intensity of the blue coloration of eggs were found to be positively correlated (Moreno et al. Testosterone increases bioavailability of carotenoids: insights into the honesty of sexual signaling. Explosive eversion and functional morphology of the duck penis supports sexual conflict in waterfowl genitalia.
Polygynandry, face-to-face copulation and sperm competition in the Hihi Notiomystis cincta (Aves: Meliphagidae). These results provide experimental evidence for a link between testosterone levels and immunoenhancing carotenoids that (i) reconciles conflicting evidence for the immunosuppressive nature of androgens, (ii) provides physiological grounds for a connection between two of the main signaling systems in animals, (iii) explains how these signaling systems can be evolutionary stable and honest, and (iv) may explain the high prevalence of sexual dimorphism in carotenoid-based coloration in animals.
These results support the hypothesis that duck vaginal complexity functions to exclude the penis during forced copulations, and coevolved with the waterfowl penis via antagonistic sexual conflict.
Each drives the evolution of the other's egg color and patterning, as hosts attempt to avoid exploitation by rejecting odd-looking eggs from their nests, and parasites attempt to outwit their hosts by laying eggs that will escape detection. Users will usually tailor their dosage individually, depending on results and side effects, but somewhere in the range of 2-8 tablets per day is most common. These results demonstrate that temperature has a direct effect on timing of breeding, an important step towards assessing the implication of climate change on seasonal timing.
This co-evolutionary arms race has increased variation in egg appearance both within and between species, in parasites and in hosts, sometimes resulting in the evolution of egg color polymorphisms. Also, female Eastern Bluebirds in better body condition were found to lay more colorful eggs, supporting the hypothesis that biliverdin pigmentation in eggshells reflects female condition (Siefferman et al. It has also reduced variation in egg appearance within host clutches, although the benefit thus gained by hosts is not clear. For fat loss, Clenbuterol seems to stay effective for 3-6 weeks, then it's thermogenic properties seem to subside. Toward and ecological basis of hormone-behavior interactions in reproduction of birds: In K. Clenbuterol is attractive for its pronounced thermogenic effects as well as mild anabolic properties.
A number of medical reviews have cited its outstanding potential to promote muscle gains as well as fat loss and weight loss. There have been an increasing number of American bodybuilders that are experimenting with this drug. Many athletes who use Clenbuterol claim that it promotes dramatic strength increases and a very noticeable reduction in body fat and weight loss. Some athletes claim that they enjoyed significant gains in muscle mass while using Clenbuterol. It is not banned by any athletic committee; thus, numerous professional bodybuilders have used it for the last month of contest preparation. The reason although it is fairly anabolic, and it promotes the burning of fatty acids through brown fat burning. Dosages are normally between 20-120 mcg for bodybuilders that use this.This drug becomes ineffective for its anabolic properties after 18 successive days of use. Although there is quite a bit of medical literature showing clenbuterol's potential as a bodybuilding drug, most of these studies have been done on animals; very little human data on this issue is available. Therefore, in assessing its effects in humans, you have to rely primarily on empirical and anecdotal evidence. However, with the recent wide scale use of clenbuterol by athletes, we can now gather quite a bit of evidence on what the real world effects of Clenbuterol are in weight trainers.
To say that Clenbuterol use is rampant in bodybuilding right now would be an understatement. I personally know a number of pro football players, foreign Olympic athletes, and professional bodybuilders who are using clenbuterol.
In addition, I have received feedback from at least 200 other athletes who have experimented with this novel compound.
Generally, the feedback from clenbuterol users is that the drug produces dramatic body composition alterations. One Canadian strength coach compared the results he has seen in athletes using Clenbuterol to what one might experience while using a stack of Anavar and Halotestin. Within weeks of beginning Clenbuterol therapy, many athletes notice a significant strength increase and a dramatic reduction in body fat.
The results that occur secondary to Clenbuterol administration seem to occur equally in men and women as well as young and old.
The trick of using Clenbuterol successfully seems to be avoiding receptor downgrade which occurs rapidly with the use of this beta agonist. In fact, one clinical study showed downgrade at receptor as much as 50% experienced after using Clenbuterol for as little as 18 days consecutively. The same study showed that attenuation can be avoided if Clenbuterol is taken in a '2 day on' then '2 day off' pattern.
Athletes using Clenbuterol in this manner have reported much greater results than those who use the product continualy which seems to support the theory that attenuation can be at least partially avoided by staggering the dosage. Athletes have also made a habit of cycling Clenbuterol in an effort to minimize side effects as well as prevent receptor downgrade. It allows people to keep eating large amounts of foot without adding excess adipose tissue (fat). Alternative To Steroids: Clenbuterol has a mild steroid like affect and can be used by athletes that do not use anabolic steroids, to increase lean body mass.
