A spermatid is the haploid male sexual cell formed after meiosis from spermatocytes that eventually matures into a spermatozoon. Spermatogenesis is the formation of male sexual cells or sperms in the testis, the male reproductive organ. Spermatogonia, the stem cells in the testis, differentiate to form spermatocytes during spermatogenesis. Spermatogenesis. The process of producing mature sperm is called spermatogenesis. Sperm are produced in the seminiferous tubules of the testes and become mature in the epididymis. The entire process takes about 9 to 10 weeks. If you look inside the seminiferous tubule shown in Figure below, you can

Spermatogenesis: The nucleus undergoes condensation in the sperm. Oogenesis: No nuclear condensation is found in the ovum. Food Reservation. Spermatogenesis: Little food is reserved in the sperm. Oogenesis: A lot of food and biochemicals are reserved in the ovum. Motility. Spermatogenesis: Spermatogenesis produces motile gametes. If the pituitary gland is removed, spermatogenesis can still be initiated by follicle stimulating hormone (FSH) and testosterone. FSH stimulates both the production of androgen-binding protein (ABP) by Sertoli cells and the formation of the blood-testis barrier. ABP is essential to concentrating testosterone in levels high enough to initiate Abstract and Figures. Spermatogenesis is a long and complex process that, despite the shared overall goal of producing the male gamete, displays striking amounts of interspecific diversity.

We explore five specific aspects of spermatogenesis from an evolutionary perspective, namely: (i) interspecific diversity in the number and morphology of sperm produced; (ii) the testicular organizations and stem cell systems used to produce them; (iii) the large number and high evolutionary rate of genes underpinning spermatogenesis; (iv) the
Sperm cells are the male gametes, which are otherwise known as their reproductive cells or their sex cells. The purpose of a sperm cell is to fertilize the female gamete, otherwise known as the egg cell in a process known as sexual reproduction. The male testis is the site of sperm cell production. Male humans typically have two of them, which 3. A spermatozoon, in plural spermatozoa, or sperm cell is the male reproductive cell that is produced in the man´s testicles in a process called spermatogenesis. The sperm cell´s function is to enable sexual reproduction through its union with the female egg during fertilization. For this to happen, it is very important that the sperm cells .
