Nulliparity is a condition that has been associated with the development of some oncological gynecological diseases. Cancer mortality rates in Catholic nuns (breast, ovarian and uterine) is higher than in general population , and nulliparous women appear more susceptible to these three cancers, as compared to parous women, thus suggesting that pregnancy represents a protected time . It is suggested that in nulliparous women, the increased number of cycles between menarche and menopause expose to an increased risk of hormone-dependent cancers.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
