The epididymis is a duct-like organ that connects the testis to the vas deferens and is comprised of four anatomical regions: the initial segment, caput, corpus, and cauda. Sperm maturation occurs during epididymal transit by the interaction of sperm cells with the unique luminal environment of each epididymal region. The purpose of the organs of the male reproductive system is to perform the following functions: Unlike the female reproductive system, most of the male reproductive system is located outside of the body.

The male reproductive system is mostly located outside of the body. WebA. According to Gist et al. It commonly starts in the tubular testicle structures that help produce sperm. The primary hormones involved in the functioning of the male reproductive system are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone. c. testicular tumor. For many men, hormone production may remain normal into old age, while others may have declining hormone production earlier on. A semen analysis can help you determine if your sperm count is normal. Radioactive "seeds" are associated with: There is a system of tiny tubes in the testicles. Spermatogenesis is the process of generation of male reproductive cells from spermatogonial stem cells in the seminiferous epithelium of the testis.
