is spermatosis same as spermiogenesis or is it some thing different and what do u mean by the secretions of endometrium during menstrual cyle  (what are its secretions)???clarify. both the doubts plssss

Dear Student, Spermatogenesis is the process of formation of spermatozoa from germinal cells. It involves conversion of diploid structure into haploid structure. Spermiogenesis is the process of differentiation of spermatozoa from a spermatid. It changes a haploid structure into another haploid structure. Secretion of endometrium: When ovulation takes place endometrium enters the secretory phase which means it prepares itself for pregnancy(lining undergoes series of changes). If pregnancy does not occur the endometrium which gets thickened will be shed during menstruation. Thank You!
