In what structure does spermatogenesis occur
WebAnswer. Sperm production, otherwise known as spermatogenesis, occurs in the male testes in structures called the seminiferous tubules. Overall, spermatogenesis aims to convert diploid primary germ cells into haploid mature sperm cells, which are able to fertilize a female’s egg cell. WebUnlike regular meiosis (such as with spermatogenesis), the first polar body never divides, and instead degrades through atresia. Only the primary oocyte undergoes Meiosis II (but only in the presence of a sperm!). If this happens, a second polar body is produced (which is also degraded).

WebThe germline consists of germ cells, which undergo meiosis and give rise to gamete cells, which eventually develops into gametes. Gametogenesis includes two important processes: Spermatogenesis and Oogenesis. Spermatogenesis is a process in which formation of sperms occurs in males. Oogenesis refers to the formation of the ovum in females. Web13 dec. 2024 · The compact head, which has lost most of its cytoplasm, is key in the formation of a streamlined shape.
