Sperm cells are produced in the seminiferous tubules. Toward the lumen of the seminiferous tubules are layers of more and more mature sperm cells.
It's in the epididymis that lays next to the testes.
epididymis
Final maturation of sperm cells occurs in the epididyrhis. The site for sperm maturation is in the epididymis. The testes are used for the production of sperm and testosterone.
In the epididymis.
Testosterone.
Spermatogenesis
epididymis
Its the wonderful thing known as the testicles. The testicles produce sperm and store sperm.Actually, the testicles only produce sperm, they do not store it. Sperm is stored in the epididymis.
Follicle Stimulating Hormone stimulates follicle and egg maturation in females and stimulates sperm production and maturation in males. Therefore low levels of FSH slows spermatogenesis.
The Sertolli cells, which are located in the seminiferous tubules of the testis.
It provides support and protection while enabling movement. It functions to store calcium and phosphorus. It is the site of blood cell production in adults. It is the site of maturation of B-lymphocytes.
Sperm cells have an immature stage in the testes and maturation occurs as the sperm move through the testicular system. There can be multiple reasons for ejaculate to contain immature sperm cells. The mechanical reason is high frequency of intercourse. Another reason for failure would occur in the epididymis where the Sertoli cells facilitate maturation. Causes can be adult mumps, hormonal issues, drugs/medication, radiation, genetic anomalies and excess heat.
The first hormone that is involved in the maturation of the egg and sperm is the gonadotropin - releasing hormone(GnHR). This hormone is secreted by the hypothalamus, and it stimulates release of two gonadotropin hormones released by the pituatury gland. The leutenizing hormone (LH) and follicle stimulating hormone (FSH). And these two pituatury gland gonadotropins are the key hormones for the maturation of egg and sperm.
