Success rates. IVF success rates are the percentage of all IVF procedures that result in favourable outcomes. Depending on the type of calculation used, this outcome may represent the number of confirmed pregnancies, called the pregnancy rate, or the number of live births, called the live birth rate. Due to advances in reproductive technology ...
Age and female fertility. Female fertility is affected by age and is a major fertility factor for women. A woman's fertility is in generally good quality from the late teens to early thirties, although it declines gradually over time. [1] Around 35, fertility is noted to decline at a more rapid rate. [1] At age 45, a woman starting to try to ...
Pregnancy rates range widely in published series, with a large study in 1991 observing the best outcome of 76% pregnancy success rate with vasectomy reversals performed within 3 years or less of the original vasectomy, dropping to 53% for reversals 3–8 years out from the vasectomy, 44% for reversals 9–14 years out from the vasectomy, and 30 ...

Typically pregnancy success rates per IUI cycle is approximately 12.4%. According to a study from 2021, lesbian women undergoing IUI had a clinical pregnancy rate of 13.2% per cycle and 42.2% success rate given the average number of cycles at 3.6.
The success rate of reciprocal IVF heavily depends on the age of the birth mother. For women under age 35, there is a 41-43% success rate. For women over 40, there is a 13-18% success rate. As IVF is not always successful on the first attempt, it is important that couples understand that multiple cycles may be required to achieve a pregnancy.
