Testosterone also stimulates sperm production in the seminiferous tubules and activates the prostate gland and seminal vesicles to produce their secretions. The release of testosterone is ...

Sperm is in semen, but they are technically not the same. Find out what semen is made of (besides sperm) and more details ...

Male reproductive system is straightforward. Testes - composed of seminiferous tubules which produce large numbers of spermatozoa Vas deferens - spermatozoa leave testes and accumulate in the vas ...

Tunica, a double-layered fibrous tissue, surrounds each testis. The testicles are made up of lobules, which contain seminiferous tubules. These narrow tubes produce and carry sperm to the rete ...

Figure 1: Specific cell associations that define the stages of the cycle of the seminiferous epithelium are present within distinct regions that exhibit differential light absorption patterns.

For the first time, a molecular mechanism is identified, for experimental acceleration and deceleration (rejuvenation) of sperm epigenetic aging.

Together, the findings suggested that 17α-estradiol extensively reshaped the cell populations, cellular communication, neuropeptide secretion, and neural synapse activity in aged hypothalamus, which ...

Testicular cancer and testes torsion patients also have a markedly high incidence of ASAs, [47] which may be related to radiation therapy and severe damage of seminiferous tubules. However ...
