Formation and development of sperms.
The manufacture of sperm in the male.
The formation and development of spermatozoa in the testes.
The production of sperm by the testes in the male.
Process of spermatozoa development from early stages of spermatogonia through other stages leading to spermatids and finally mature spermatozoa.
The process by which mature spermatozoa are produced in the testis. Spermatogonia, in the outermost layer of the seminiferous tubules, multiply throughout reproductive life. Some of them divide by meiosis into spermatocytes, which produce haploid spermatids. These are transformed into mature spermatozoa by the process of spermiogenesis. The whole process takes 70-80 days.
The production of mature sperm in the testis. The sperm cells originate from the outermost layer of the seminiferous tubules in the testis: these multiply throughout reproductive life and are transformed into mature spermatozoa, a process that takes up to 80 days.
The formation of mature functional spermatozoa. In the process, undifferentiated spermatogonia become primary spermatocytes, each of which divides to form two secondary spermatocytes. Each of these divides to form two spermatids, which transform into functional motile spermatozoa. In the process, the chromosome number is reduced from the diploid to the haploid number.
The progression through which spermatozoa undergo development to attain maturity, enabling them to fertilize an egg.
The generation of sperm cells.
