Artificial insemination is an assisted reproduction technique consisting of depositing spermatozoa in the uterus during the ovulation period with the goal of fertilisation and pregnancy.

Gonadotropins (LH and FSH) and adrenocorticotropin (ACTH) are pituitary hormones regulated by the corresponding hypothalamic releasing factors.
The hypothalamus is essential to life, despite its small size, as it controls the endocrine system and the autonomous nervous system.
