With the right approach — particularly the use of hCG — you can maintain testicular size, support fertility, and preserve hormonal balance. Testicular shrinkage, or testicular atrophy, can be caused by a variety of factors. When you’re on TRT, your body senses that it’s getting enough testosterone from an external source. Consulting with both medical and psychological professionals provides a comprehensive approach to restoring sexual wellness.
From there, they’re pushed along to the epididymis, another type of tube that runs along the back side of your testicle. The immature cells get the blood and nutrients they need in the tubules. It takes about 74 days for sperm cells to mature. In each of the testes, the process happens in tubes called seminiferous tubules. Cooler temperatures are better for making sperm, a process called spermatogenesis. Testicles are about two degrees Celsius lower in temperature than the rest of your body. Cleveland Clinic is a non-profit academic medical center.
By regularly tracking testosterone levels, LH, and follicle-stimulating hormone (FSH), you can adapt your TRT regimen to mitigate the risk of testicle shrinkage. When testosterone levels drop, testicular function diminishes, leading to potential shrinkage and decreased sperm production. For example, optimal testosterone levels means increased sperm counts, better fertility, healthier Leydig cell numbers and circulating androgen precursor hormones . In accordance with sperm competition theory, testosterone levels are shown to increase as a response to previously neutral stimuli when conditioned to become sexual in male rats. In males, these are usual late pubertal effects, and occur in women after prolonged periods of heightened levels of free testosterone in the blood. In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
"You can wear a jockstrap, or put a small rolled up towel under your sac to keep your testicles elevated," Baptiste says. If you’re on the unfortunate end of a kick to the nuts and there is no real trauma, elevate your testicles. "Your tunica albuginea keeps your testicles in place," he says. "In the course of your testicles moving into your scrotum, many other nerves follow suit." Over time, your kidneys settle into their place—near the middle of your back just under your rib cage—and your testicles descend to your scrotum.
"Although rare, a serious injury can cause testosterone deficiency and issues with fertility," Baptiste says. "The difference with a rupture is the size and immediacy of your swelling, and the intensity of a sharp pain." "There is a chance your testicle can die and you need surgery to put your tunica back together," Baptiste says.
