Understanding Spermatogenesis: From Spermatogonia to Sperm Spermatogenesis is the process of sperm formation occurring in the seminiferous tubules of the testicles. Diploid spermatogonia can either undergo mitosis to replenish their numbers or meiosis to form haploid spermatids, progressing from primary to secondary spermatocytes before becoming mature sperm. Leydig cells produce testosterone, essential for maturation and are located near these tubules.
Epididymis & Vas Deferens: Maturation and Transport of Sperm The epididymis serves as a storage site where immature sperm complete their maturation after being transported from the testes. The vas deferens then propels matured sperm forward through muscular contractions while adding seminal fluid produced by seminal vesicles and prostate glands during ejaculation, enhancing nutrition and protection for the sperm.
Penile Anatomy: Facilitating Ejaculation Final transport occurs via penile urethra where lubricating secretions assist in expelling semen outside during ejaculation. Key structures include erectile tissues like corpus cavernosum that engorge with blood leading up to an erection, facilitating successful reproduction processes within male anatomy.
