Female infertility refers to infertility in women. It affects an estimated 48 million women, [2] with the highest prevalence of infertility affecting women in South Asia, Sub-Saharan Africa, North Africa/Middle East, and Central/Eastern Europe and Central Asia. [2] Infertility is caused by many sources, including nutrition, diseases, and other ...
Infertility in polycystic ovary syndrome. Infertility in polycystic ovary disease (PCOS) is a hormonal imbalance in women that is thought to be one of the leading causes of female infertility. [1][2][3][4] Polycystic ovary syndrome causes more than 75% of cases of anovulatory infertility. [5]
Common in males: low sperm count, abnormal sperm morphology. Frequency. 113 million (2015) [1] Infertility is the inability of an animal or plant to reproduce by natural means. It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects).
Poor ovarian reserve. Poor ovarian reserve is a condition of low fertility characterized by 1): low numbers of remaining oocytes in the ovaries or 2) possibly impaired preantral oocyte development or recruitment.

Hyperprolactinaemia is the most common cause of AHH. It is a well-established cause of infertility in both male and female mammals. [6] Prolactin inhibits GnRH neurons and therefore inhibits the subsequent release of LH, FSH and sex steroids. The mechanism of prolactin induced inhibition of GnRH release is poorly understood. [6]
Menopause, also known as the climacteric, is the time when menstrual periods permanently stop, marking the end of reproduction. [1][6] It typically occurs between the ages of 45 and 55, although the exact timing can vary. [7] Menopause is usually a natural change. [3]
Endometriosis and its complications are a major cause of female infertility. Endometriosis is a dysfunction characterized by the migration of endometrial tissue to areas outside of the endometrium of the uterus. The most common places to find stray tissue are on ovaries and fallopian tubes, followed by other organs in the lower abdominal cavity ...
