Life of a sperm for feilisation is:
Correct Answer: 72 hours
Description: 72 hours "Feilisable life span of oocyte ranges from 12 to 24 hours whereas that of sperm is 48 to 72 hours." Since 48 hours and 72 hours both are given in options therefore this leaves us in doubt. CtinicalGynaecologic endocrinology and-lnfeility by Leon Spiroff 7/e, p 1159 says "Normal sperm can survive in the female reproductive tract & retain the ability to feilize an egg for at least 3 days, but an oocyte can be successfully feilised tor only 12 to 24 hours after it is released". So, now their is no confusion as option c being the correct choice. As far as the credibility of this book is concerned. I being a Gynaecologist can tell you, it holds the same status in Gynae as Harrison in medicine. Progesleroneo (Predominantly) -24. secreted bv corpus
