The technique, first attempted by Steptoe and Edwards [1] and later pioneered by endocrinologist Ricardo Asch, allows fertilization to take place inside the woman's uterus. [ 2 ] With the advances in IVF the GIFT procedure is used less as pregnancy rates in IVF tend to be equal or better and do not require laparoscopy when the egg is put back.

The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. [1] [2] The first reported case of artificial insemination by donor occurred in 1884: William H.

In December 1983, the first baby was born using this method which happened to be twins. [24] The ability to freeze and preserve a woman's eggs to be used at a later date has also had impacts on IVF use. In 1986, Dr. Christopher Chen reported the first pregnancy which used oocyte cryopreservation (frozen eggs). The ability to freeze sperm has ...
Many factors can affect fertility, and these factors can affect one or both partners. Damage to the woman's eggs or the man's sperm, or a change in the hormones needed to regulate the normal menstrual cycle are just a few things that can cause problems with fertility.

A woman's fertility is affected by her age. The average age of a girl's first period is 12–13 (12.5 years in the United States, [4] 12.72 in Canada, [5] 12.9 in the UK [6]), but, in postmenarchal girls, about 80% of the cycles are anovulatory in the first year after menarche, 50% in the third and 10% in the sixth year.

Since then, there have been many milestones for reproductive medicine, including the birth of Louise Brown, the first baby to be conceived through IVF in 1978. [3] Despite this, it was not until 1989 that it became a clinical discipline thanks to the work of Iain Chalmers in developing the systematic review and the Cochrane collection. [2]
