As with most fertility procedures, success depends on the couple's age and the woman's egg quality. It is estimated that approximately 25–30% of GIFT cycles result in pregnancy, [5] with a third of those being twins or triplets, etc. The First GIFT baby in the UK was Todd Holden born in October 1986.

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.

The absence of fertility in children is considered a natural part of human growth and child development, as the hypothalamus in their brain is still underdeveloped and cannot release the hormones required to activate the gonads' gametes. Fertility in children before the ages of eight or nine is considered a disease known as precocious puberty.
The Billings ovulation method is a method in which women use their vaginal mucus to determine their fertility. [3] It does not rely on the presence of ovulation, rather it identifies patterns of potential fertility and obvious infertility within the cycle, whatever its length.
