In vitro fertilization (IVF) is a procedure in which eggs (ova) from a woman's ovary are removed, they are fertilized with sperm in a laboratory procedure, and then the fertilized egg (embryo) is returned to the woman's uterus.

The pituitary signal to her ovaries to prepare an egg for ovulation. The pituitary hormones — follicle-stimulating hormone (FSH) and luteinizing hormones — follicle-stimulating hormone (FSH) and luteinizing hormone (LH) — are involved in stimulating the ovaries to bring an hormone (LH) — are involved in stimulating the ovaries to bring an egg to ovulationegg to ovulation..
** A large boost in LH carries a message to the ovarian follicle to A large boost in LH carries a message to the ovarian follicle to release its egg (ovulate). A woman is most fertile at the time of release its egg (ovulate). A woman is most fertile at the time of ovulation — around day 14 of her menstrual cycle — although the ovulation — around day 14 of her menstrual cycle — although the exact time of ovulation varies among women due to different exact time of ovulation varies among women due to different lengths of menstrual cycles.lengths of menstrual cycles.
** The egg is then captured by a fallopian tube and is viable for about 24 hours, but its best chance of being fertilized is within the first 12 hours following ovulation. For pregnancy to occur, a sperm must unite with the egg in the fallopian tube during this time.
** Sperm are capable of fertilizing the egg for up to 72 hours and must be present in the fallopian tube at the same time as the egg for conception to occur. If fertilized, the egg moves into the uterus two to four days later. There it attaches to the uterine lining and begins a nine-month process of growth.
Types of infertilityTypes of infertilityInfertility was divided into two types:
Type I: never achieving a recognized pregnancy ,Type II: conception but no live birth .
Infertility is broken down into male factor, female factor.

TREATMENT OF INFERTILITY
Ovulation induction:
1. Clomid (Clomiphene)/ Tamoxifen: Clomid blocks the estrogen receptors on the hypothalamus causing them to “think” there is estrogen deficiency
2. Bromocriptine / Cabergoline / Quinagolide: reduce prolactin secretion
3. hMG (pergonal, menogon) : hMG contains both FSH and LH hormones
4. FSH (metrodin) : stimulates the ovaries to produce multiple follicles .
5. LH (luteinizing hormone) : Gonal F and Puregon
6. hCG (profasi and pregnyl ):
7. pulsatile GnRh (Fertiral )
