While some studies suggest that a family history increases risk, and other researchers worry about environmental factors, the only well-established contributor to testicular cancer is cryptochicism, undescended testes. Just 30 years ago, 90 percent of men with testicular cancer died from the disease; today more than 90 percent are cured.
Philosophers proclaim that all men should examine their lives; the American Cancer Society suggests that young men should examine their testicles. Objectives: We investigated whether in utero exposure to PFOA and PFOS affects semen quality, testicular volume, and reproductive hormone levels. In the manuscript originally published online, some of the p-values in Table 1 were incorrect. The prospective design of the present study enables us to investigate the hypothesis that in utero exposure to PFOA and PFOS is associated with reduced semen quality and testicular size, as well as altered reproductive hormones, in adult men. Differences across tertiles of maternal PFOA and PFOS exposure were estimated using one-way analysis of variance (ANOVA) tests and chi-square tests. Trend tests on crude sperm concentration and total count did not indicate significant associations with PFOA exposure (Table 2). Table 2 – Semen, testicular size, and reproductive hormone characteristics for 169 young Danish men stratified by tertiles of maternal serum PFOA concentrations at pregnancy week 30.
No significant trends of associations between the percentage of progressive spermatozoa and PFOA were indicated in either crude or adjusted results based on the manual assessment (Table 2).
For associations of in utero exposure to PFOA and sperm morphology, semen volume, or testicular volume, we observed no significant trends or differences between PFOA exposure groups (Table 2).

In about 3 percent of boys, one testicle fails to descend by the time of birth, as it should.
If the ultrasound suggests cancer, the patient should have blood tests for tumor markers, proteins produced by the cancer cells.

In nearly all cases, it involves the surgical removal of the abnormal testicle through an incision in the lower abdomen rather than the scrotum. They are used as surfactants in many industrial processes and consumer products, such as oil and water repellents for fabrics and food-packaging materials (Kissa 2001). Outcome variables included semen parameters [sperm concentration, total sperm count, semen volume, percentage progressive spermatozoa (rapidly progressive + slowly progressive), and percentage morphologically normal spermatozoa], mean testicular volume (estimates were comparable for left and right volumes separately), and reproductive hormones (testosterone, estradiol, LH, FSH, SHBG, and inhibin B).
We tested crude trends by Spearman’s rank correlation test and adjusted trends by multivariable regression analyses by entering PFOA and PFOS as continuous variables in the model. Prenatal exposure to PFOS was not related to any of the semen parameters, testicular volume, or reproductive hormones.
If this is not repositioned surgically, usually between the boy’s first and second birthdays, testicular cancer is eleven times more likely to develop in this undescended testicle. Although the operation, called a radical inguinal orchiectomy, is surgically straightforward, it’s psychologically threatening to many men.
Proliferation and functional maturation of Sertoli cells, and their relevance to disorders of testis function in adulthood. Anti-Mullerian hormone in men with normal and reduced sperm concentration and men with maldescended testes.
Testicular signaling is the potential target of perfluorooctanesulfonate-mediated subfertility in male mice. WHO Laboratory Manual for the Examination of Human Semen and Sperm–Cervical Mucus Interaction. For example, in inguinal hernia can produce a soft swelling in the scrotum, but the testicle itself is normal. It is reassuring, however, to know that sexual function remains intact because the healthy testicle is not disturbed by the operation. The procedure is easy to master: simply roll your testicle gently between your thumb and your first two fingers (see illustration).

Studies of adult male rats showed that PFOA exposure may cause reduced testosterone levels and increased estradiol levels (Lau et al. Differences between the two upper tertiles versus the lowest tertile were tested by two-sample Wilcoxon rank-sum (Mann–Whitney) test (crude results) and by multivariable regression analysis for each of the outcome variables, with low PFOA and PFOS groups as referents. CASA using CRISMAS Clinical software supported the results from the manual assessment of semen analysis (see Supplemental Material, Table S2).
In reality, there is no relation of sexual power with the size of testes and skin and elasticity of scrotum. 2007), and a study on sexually mature mice indicated that PFOS exposure might affect testicular signalling, causing reduced serum testosterone and decreases in epididymal sperm counts (Wan et al. Testicular volume self-measurements were performed using a Prader orchidometer, a method reported to be valid for testicular size measurement (Ramlau-Hansen et al.
Normal testicles are smooth and slightly spongy; you are checking for a firm, pea-sized lump, an increase in size, or an abnormally firm texture. In 2008, sons of the pregnancy cohort were invited to answer an Internet-based questionnaire on health and lifestyle habits, and in 2008–2009 they were asked to undergo a physical examination in which they donated a semen sample (which they had produced at home), gave a blood sample to be analyzed for reproductive hormones, and self-measured testicular volumes (Vested et al.
Tell your doctor if you notice an abnormal mass, unusual firmness, or unexpected tenderness of the testicle.
Each man provided written informed consent prior to participation, and the study was approved by the Central Denmark Region Committees on Health Research Ethics (registration number M-20070157).
