Ovulation induction is the stimulation of ovulation by medication. It is usually used in the sense of stimulation of the development of ovarian follicles [ 1 ] [ 2 ] [ 3 ] to reverse anovulation or oligoovulation .
According to NICE guidelines of in vitro fertilization, an anti-Müllerian hormone level of less than or equal to 5.4 pmol/L (0.8 ng/mL) predicts a low response to ovarian hyperstimulation, while a level greater than or equal to 25.0 pmol/L (3.6 ng/mL) predicts a high response. [8]
Other medications in this class include tamoxifen and raloxifene, although both are not as effective as clomiphene and are thus less widely used for fertility purposes. [7] They are used in ovulation induction by inhibiting the negative feedback of estrogen at the hypothalamus. As the negative feedback of estrogen is inhibited, the hypothalamus ...
The main medications used for induction of final maturation are human chorionic gonadotropin (hCG) and GnRH agonist. In fresh (rather than frozen ) autologous cycles of in vitro fertilization , final oocyte maturation triggering with GnRH agonist instead of hCG decreases the risk of ovarian hyperstimulation syndrome but decreases live birth rate .
Gonadotropin preparations are drugs that mimic the physiological effects of gonadotropins, used therapeutically mainly as fertility medication for ovarian hyperstimulation and ovulation induction. [1] For example, the so-called menotropins consist of LH and FSH extracted from human urine from menopausal women. [2] There are also recombinant ...

Ovulation induction, reversing anovulation or oligoovulation; Final maturation induction of oocytes; Controlled ovarian hyperstimulation, stimulating the development of multiple follicles of the ovaries in one single cycle; Physiologic hormonal stimulation of folliculogenesis
Clomifene has been used almost exclusively for ovulation induction in premenopausal women, and has been studied very limitedly in postmenopausal women. [64] Clomifene was studied for treatment and prevention of breast cancer, but issues with toxicity led to abandonment of this indication, as did the discovery of tamoxifen. [65]
