Estrogen is the major female sex hormone secreted primarily by the ovaries and in small amounts by the adrenal gland. It plays an important role in the onset of puberty, development of secondary sexual characteristics, such as breasts, and pubic and armpit hair. Estrogen also helps regulate the menstrual cycle and also controls breast changes during pregnancy.Peer review refers to the work done during the screening of submittedÂ manuscriptsÂ and funding applications. This process encourages authors to meet the acceptedÂ standardsÂ 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.
