==== Ovarian reserve ====
Studies of hormone levels and ovarian reserve have demonstrated no significant changes after female sterilization, or inconsistent effects.<ref>{{Cite journal|last1=Ercan|first1=Cihangir Mutlu|last2=Sakinci|first2=Mehmet|last3=Coksuer|first3=Hakan Ko|last4=Keskin|first4=Ugur|last5=Tapan|first5=Serkan|last6=Ergun|first6=Ali|date=January 2013|title=Ovarian reserve testing before and after laparoscopic tubal bipolar electrodesiccation and transection|journal=European Journal of Obstetrics, Gynecology, and Reproductive Biology|volume=166|issue=1|pages=56–60|doi=10.1016/j.ejogrb.2012.09.013|issn=1872-7654|pmid=23036487}}</ref> Evidence does not indicate a strong association between tubal ligation and earlier onset of menopause.<ref>{{multiref2
