A blastocyst is an embryo that has developed in culture in the IVF laboratory for at least five days after egg retrieval and has divided into two different cell types.
There is now abundant evidence that transferring blastocyst embryos into the uterus five or six days after egg retrieval, results in higher implantation rates per embryo transferred compared to a day three embryo transfer.
Traditionally, in an IVF cycle, embryos were transferred to the uterus on the second or third day of development and initial embryonic cell division. Previously, laboratory culture media could only sustain an embryo’s growth for about three days in vitro. La Jolla IVF is fortunate to have an embryology team that is highly skilled and a laboratory that is technologically advanced. This newer "sequential media" attempts to reproduce the natural environment of the maternal reproductive tract. In general, a blastocyst or embryo transfer procedure is more advantageous for patients who develop a large number of eggs and embryos.
At La Jolla IVF however, many of the patients who are regarded as “poor prognosis” in terms of their ultimate success rate for IVF, choose to undergo what we term “embryo banking” cycles. Over the past several years, patients at La Jolla IVF have completed hundreds of fresh and frozen blastocyst embryos transfers. If you are trying to get pregnant, you should get a copy of the Essential Guide for Getting Pregnant. Smoking – Smoking during pregnancy is estimated to account for 20 to 30% of low-birth weight babies, up to 14 % of preterm deliveries, and about 10% of all infant deaths according to the American Lung Association.
Drinking Alcohol – There is no safe amount of alcohol to consume while you are pregnant.
Recreational Drug Use – Recreational Drug Use during pregnancy can increase the chance of miscarriage, low birth-weight, premature births, developmental delays, and behavioral and learning problems. Prescription Drugs – There are many prescription drugs that are teratogenic (cause birth defects). Stress – Stress has been linked to delayed or missed periods which can cause difficulty tracking ovulation and getting pregnant.
Herbs – Most herbs and herbal remedies are not mandated by the FDA, and therefore, there is little to no research on the effect they have on pregnancy. Discuss any herbal or natural remedies you may be using with your healthcare provider.
Caffeine – Some studies have shown a link between high levels of caffeine consumption and delayed conception. Get lots of sleep – Eight hours of sleep is recommended if you are trying to become pregnant. Your weight can play a significant role during conception and pregnancy. When planning to conceive you want to avoid being over or under weight.
It is important that you see your doctor before you become pregnant. There are medical conditions that you may not be aware of that can affect your pregnancy. High blood pressure – If you have high blood pressure before pregnancy, you must closely monitor your high blood pressure during pregnancy.
Anemia – A complete blood count (CBC) can measure your hemoglobin, red and white blood cell count, and the appearance of your platelets. Anemia can cause weakness and fatigue during pregnancy. Thyroid problems – The test to check for thyroid issues consists of a blood test which measures your thyroid-stimulating hormone (TSH). Hyperthyroidism (overactive) can lead to premature birth and low birth weight if left untreated. STDs – It is best to know if you have an STD before getting pregnant, since some STDs can cause pregnancy complications.
Immunity to Rubella (measles) – The March of Dimes recommends that all women be tested for immunity to rubella before they become pregnant and that they consider being vaccinated at that time if they are not immune. Immunity to Varicella (chicken pox) – As with rubella it is recommended that all women be tested for immunity to varicella before they become pregnant and that they consider being vaccinated at that time if they are not immune.

The Association is only able to accomplish our mission with the commitment of people like you. The surface cells are termed the trophectoderm and will eventually become the placenta and the inner cells, termed inner cell mass will become the fetus. During the first few days, the embryo relies on the egg cell (from the mother) for all its growing nutrients. An embryo reaching the blastocyst stage has an increased chance of implantation as opposed to a day 3 embryo (all things being equal regarding a healthy uterus). La Jolla IVF’s embryology team has moved systematically towards refining the techniques in the laboratory which now enable many of our patients to avail themselves to transferring blastocysts as opposed to the older more traditional methodology of day 3 transfers. Research throughout the late 90?s identified that as the embryo develops, its nutritional requirements change due to metabolic factors.
It requires much more time and effort to sustain the dynamic process of embryo development to blastocyst stage. These blastocyst culture conditions do not improve the health or viability of an individual embryo-sequential media does not transform a poor embryo into a good embryo, rather it allows embryos capable of sustained growth to continue growing in the culture media and reach their maximum inherent capability. Because only some embryos are capable of developing into blastocysts, it is possible to have no embryos survive to day 5 to transfer. The optimization of a blastocyst cryopreservation program mandates a comprehensive approach. Knowing that the first few weeks of pregnancy are the most vital to the development of the baby, a mother should be healthy and avoid any harmful activities and substances near the time of conception. This ebook is one of the easiest and up to date resources for getting the information and tips you need to get pregnant quickly and easily.
For example, most studies show that the greatest risk of exposure to pesticides is during the first three to eight weeks of the first trimester when the neural tube development is occurring.
A few studies have shown that there may be an increase in miscarriages among women who consume more than 200 mg (one 12oz cup of coffee) a day versus those who do not consume any caffeine. Make sure that you are getting lots of vitamins in your diet, and start taking folic acid now. Pregnancy increases the chances of diabetes, and it can make it hard for a mother who is already suffering from diabetes. The Centers for Disease Control and Prevention (CDC) recommends that a woman wait at least 4 weeks after receiving the vaccination before trying to conceive.
The CDC recommends that a woman wait at least 4 weeks before trying to conceive after receiving the vaccination. Your tax deductible contribution provides valuable education and more importantly support to women when they need it most. A healthy blastocyst should hatch from its shell (zona pellucida) by the end of six days or earlier and is then ready to begin to implant within the lining of the uterus. However, in order to survive post day three or four, the embryo must activate its own genes so that it can carry on growing and dividing. It is believed that the improved implantation rates following a blastocyst transfer is due to selection of the "best" embryos. IVF practitioners were aware that day three embryo transfers were too early when compared to what happens in naturally conceived pregnancies. This research led to the development of different laboratory culture media for the embryo’s specific developmental stages. Our embryologists use specific media to facilitate the embryos development to the blastocyst in vitro during their first three days in culture inside the IVF laboratory.


The ability to develop embryos to the blastocyst stage allows our embryology team to have greater certainty about which embryos are more likely to implant.
The embryos that are frozen will be thawed and in combination with the fresh embryos and all the resulting embryos may undergo PGD (not mandatory) on day 3 of in vitro culture (see section on Preimplantation Genetic Diagnosis (PGD) for full explanation).
An appropriate embryo culture system with attention to the protein supplement and a low oxygen environment has been shown to increase the number of blastocysts available for cryopreservation, improve the quality of the inner cell mass and blastocysts post-thaw survival rate.
In our egg donation and surrogacy cases, the ongoing pregnancy rate is over 80% per transfer using blastocysts. Before you become pregnant you want to make sure that you cut out any habits that are harmful for your baby. You may find it helpful to employ relaxation techniques or yoga to help moderate your stress level. Ask yourself if you want to lose weight, gain weight, build muscle, or improve lung capacity. Keeping track of your cycle will also help you track your ovulation and increase your chance of pregnancy. You might start on some fertility supplements to make sure you are getting all the nutrients you need. Studies have shown that folic acid (300-400mcg a day) can help reduce the risk of neural tube defects when taken before conception.
If chlamydia is left untreated, it can also lead to Pelvic Inflammatory Disease (PID) which can cause infertility.
Unfortunately, not all embryos are able to grow past this milestone and in fact only about one third of embryos are capable of becoming blastocysts.
In a naturally conceived pregnancy, the embryo reaches the uterus on day four or five because it grows and divides in the fallopian tube for several days after fertilization. These blastocyst culture conditions do not improve the health or viability of an individual embryo, i.e.
The question as to whether the embryos that did not grow into blastocysts could still have implanted if they were transferred on day 3, is not able to be definitively answered at this time. One of the major limiting factors with doing well with this type of treatment (besides the normal versus abnormal results of the PGD) is the ability of the IVF laboratory to sustain the embryos’ growth in the incubators while PGD is being performed and to enable those embryos that are inherently capable to continue to grow to blastocysts.
These results are being achieved in our program by us routinely transferring a maximum of two blastocyst embryos.
If an embryo can propel itself into becoming a blastocyst in vitro then it would appear that nature has sent us a message that these embryos are the product of a "survival of the fittest" test. Barry Behr, our Laboratory Director developed one of the first media to successfully grow embryos to the blastocyst stage.
In patients with few embryos on day 3 or where no embryo selection is needed, it is still a rational approach to perform a day 3 transfer (if the patient wishes to do a transfer on their first fresh cycle) as opposed to trying to grow these few embryos to blastocysts and then potentially having no embryos to transfer. This option has dramatically lowered the risk of patients having to deal with the stress, adversity and dilemma of carrying higher order multiples (triplets or more). Yoga is an excellent choice for exercise because it incorporates posture, breathing, and concentration techniques which will be beneficial for you during labor. Talk with your healthcare provider about what is best for you. For more information on the suggested amount of vitamins to consume during pregnancy (which is the same for preconception) look at our chart on Essential Nutrients & Vitamins. Our embryology team is constantly upgrading both laboratory equipment and their expertise and we are confident that these advances will ultimately translate into even higher pregnancy rates for patients.
