Spermatogenesis Overview:Spermatogenesis is the process of sperm cell development occurring in the seminiferous tubules over approximately 74 days.

Q7: Hormonal basis of events A and B; two phases of spermatogenesis (2+2 marks) (Aponeurosis — Embryology Question Bank)
Two phases of spermatogenesis: spermatocytogenesis (proliferation and meiotic division of spermatogonia); spermiogenesis (differentiation of spermatids into mature spermatozoa) (Aponeurosis — Embryology Question Bank)
Sertoli cells support spermatogenesis; Leydig cells secrete testosterone; peritubular myoid cells contract; germ cells form spermatozoa (Aponeurosis — Histology Question Bank)
Associated with increased infertility risk (impaired spermatogenesis from higher intra-abdominal temperature) (Female & Male Genital Pathology: Ulcers, HPV, Endometriosis, Pre-eclampsia)
Leydig cell hyperplasia reflects increased testosterone-producing tissue, consistent with elevated testosterone (though paradoxically this can occur alongside impaired spermatogenesis causing infertility). (Male Reproductive & Urinary Tract Pathology MCQs | MKU Year 3 Medicine)
