IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy, in which a fertilised egg is implanted into a surrogate’s uterus, and the resulting child is genetically unrelated to the surrogate. The first successful birth of a child after IVF sex before ivf, Louise Brown, occurred in 1978.
Louise Brown was born as a result of natural cycle IVF where no stimulation was made. This section does not cite any sources. From Latin meaning “in glass”, the term “in vitro” is used because early biological experiments involving cultivation of tissues outside the living organism from which they came, were carried out in glass containers such as beakers, test tubes, or petri dishes. Today, the scientific term “in vitro” is used to refer to any biological procedure that is performed outside the organism in which it would normally have occurred, to distinguish it from an in vivo procedure, where the tissue remains inside the living organism within which it is normally found. IVF may be used to overcome female infertility where it is due to problems with the fallopian tubes, making in vivo fertilisation difficult. According to UK’s NICE guidelines, IVF treatment is appropriate in cases of unexplained infertility for women that have not conceived after 2 years of regular unprotected sexual intercourse. IVF success rates, the percentage of all IVF procedures which result in a favourable outcome.
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. Maternal age: Younger candidates of IVF are more likely to get pregnant. Women older than 41 are more likely to get pregnant with a donor egg. Reproductive history: Women who have been previously pregnant are in many cases more successful with IVF treatments than those who have never been pregnant. Due to advances in reproductive technology, IVF success rates are substantially higher today than they were just a few years ago.
The live birth rate is the percentage of all IVF cycles that lead to a live birth. This rate does not include miscarriage or stillbirth and multiple-order births such as twins and triplets are counted as one pregnancy. Birth rates in younger patients were slightly higher, with a success rate of 35. 21 and younger, the youngest group evaluated. Success rates for older patients were also lower and decrease with age, with 37-year-olds at 27. The live birth rates using donor eggs are also given by the SART and include all age groups using either fresh or thawed eggs. Because not each IVF cycle that is started will lead to oocyte retrieval or embryo transfer, reports of live birth rates need to specify the denominator, namely IVF cycles started, IVF retrievals, or embryo transfers.
