Most of these patients have multiple pituitary hormone deficiencies. [5] 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.
Human genetic variants that likely cause dysregulation of critical meiotic processes have been identified in 14 female infertility associated genes. [53] A major cause of female infertility is premature ovarian insufficiency. [54] This insufficiency is a heterogeneous disease that affects about 1% of women who are under the age of 40. [54]
In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from their ovaries and letting a man's sperm fertilise them in a culture medium in a laboratory.

It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects).
Androgen deficiency is a medical condition characterized by insufficient androgenic activity in the body. Androgen deficiency most commonly affects women, and is also called Female androgen insufficiency syndrome (FAIS), although it can happen in both sexes. [2][3] Androgenic activity is mediated by androgens (a class of steroid hormones with ...
Specialty. Obstetrics, gynecology. Tubal factor infertility ( TFI) is female infertility caused by diseases, obstructions, damage, scarring, congenital malformations or other factors which impede the descent of a fertilized or unfertilized ovum into the uterus through the fallopian tubes and prevents a normal pregnancy and full term birth.
