In vitro fertilization (IVF) is a type of fertility treatment that involves combining eggs and sperm outside of the body in a lab. It is a complex series of procedures that can lead to a pregnancy and is used to treat infertility, a condition in which couples cant get pregnant after at least a year of trying. IVF can also be used to prevent passing on genetic problems to a child. During IVF, mature eggs are collected from ovaries and fertilized by sperm in a lab. Then, one or more of the fertilized eggs, called embryos, are placed in a uterus, where babies develop. The IVF process involves several steps, including ovulation induction, egg retrieval, fertilization, embryo culture, and embryo transfer. One full cycle of IVF takes about 2 to 3 weeks, and sometimes these steps are split into different parts, and the process can take longer. IVF is a treatment for infertility or genetic problems, and before having IVF, couples might be able to try other treatment options that involve fewer or no procedures that enter the body. IVF raises the chances of certain health risks, and it can be expensive, so its a good idea to discuss the pros and cons of fertility treatment with your treatment provider and your partner (if you have one) before you start. People choose IVF for many reasons, including infertility issues, when one partner has an existing health condition, or if theyre at an advanced maternal age. IVF is also a reproductive option for same-sex couples or people who wish to have a baby without a partner.
