Spermatogenesis | How formation of sperms occur | Gametogenesis | General Embryology

Spermatogenesis is a process in which a primordial germ cell is converted into a mature sperm. Types :- Spermatogenesis is divided into two types. (1) Spermatocytogenesis (2) Spermiogenesis Spermatocytogenesis is a process in which a primordial germ cell converted into a spermatid. A primordial germ cell appears for a very first time in a wall of yolk sac. In 4th week , it migrates to testes and converted into spermatogonia and starts mitotic divisons and forms spermatogonia type A and type B. Spermatogonia type A form again forms spermatogonia. Spermatogonia type B form primary spermatocytes . Primary spermatocyte forms 2 secondary spermatocytes by miosis 1 and 2 secondary spermatocyte form 4 spermatids by miosis 2. Spermatocytogenesis completes here. Spermiogenesis is a process in which Spermatid converted into a mature sperm. #Spermatogensis #Spermatocytogenesis #Spermiogenesis #Sperm_formation #Spermatocytogenesis_details #Embryology #Development #Abnormality #Cleft_palate #Gametogenesis #Oogenesis #Spermatogensis_in_one_shot #Urdu #Spermatogenesis_in_hindi #Medicine #Granite_of_medicine #Mbbs #Aftab_malik #Aftab #Mbbs_easy #howlifebegins #Prenatal_events #congenital_abnormality #Primordial_germ_cell #primordialgermcell #Primary_spermatocyte #secondary_spermatocyte #Spermatid #Spermatogonia #SpermatogoniatypeA #SpermatogoniatypeB #Spermatogonia #Sertoli_cells #Testes #mitosis #meiosis #doctors #mbbs #medicaleducation
