In Vitro Fertilization Success Rates Vs Other Forms of Fertility Treatment
In vitro fertilization is a fertility treatment that has helped many patients overcome infertility through safe, effective means. Once the eggs are ready for extraction, they are taken and combined with sperm, either donor sperm or the woman's partner's sperm, in a dish in a laboratory. Embryos are formed as a result and a selection process is then undertaken to determine which embryos are best fit for transfer to the uterus.
Most in vitro fertilization procedures will transfer just a few embryos to the uterus to reduce the chances of multiple births. Using multiple embryos, however, increases the procedure's chances for success. According to the Jones Institute for Reproductive Medicine at Eastern Virginia Medical School, success rates for women undergoing an IVF cycle from 2000 to 2009 were approximately 46%, while women who opted for donor egg cycles had a success rate of approximately 51%. Women who underwent cycles of cyropreserved/thawed embryo transfers had a success rate of 30%.
Intracytoplasmic sperm injection, or ICSI for short, has led to men with sperm anomalies enjoying increased success rates when undergoing in vitro fertilization. In this procedure, a single sperm is injected directly into a mature egg for fertilization. The embryo is then transferred to the woman's uterus.
According to data provided by the Jones Institute for Reproductive Medicine for the same time period, men with sperm anomalies who underwent ICSI had similar success rates to men with normal semen analysis. The fertilization rate was roughly 63% for ICSI and 71% for IVF, the pregnancy rate/transfer was 42.5% for ICSI and 44.6% for IVF, and the implantation rate was 22% for ICSI and 19% for IVF.
Intrauterine insemination is another fertility procedure that has helped couples conceive. In this procedure, the 'washed' sperm are injected directly into the woman's uterus the day after an egg is released. The idea behind this procedure is that the sperm will swim into the fallopian tubes to fertilize the egg. Success rates for intrauterine insemination, according to the Jones Institute, are less than that of in vitro fertilization. However, the procedure is less expensive than in vitro fertilization, meaning couples may afford more attempts.
There are several types of fertility drugs available, and each may have a different rate of success. Generally, fertility drugs that are directly injected into the patient come with a higher rate of multiple births than those that are taken in pill form.
It is important to remember that success rates for these and other procedures or treatments may vary on an individual basis based on several factors.
