**Core Concept**
In vitro fertilization (IVF) is a type of assisted reproductive technology (ART) that involves fertilizing an egg with sperm outside the body. IVF is primarily used to treat infertility in individuals or couples who have difficulty conceiving naturally.
**Why the Correct Answer is Right**
IVF is mainly done to overcome various types of infertility, including blocked fallopian tubes, endometriosis, unexplained infertility, and male factor infertility. The process involves stimulating the ovaries to produce multiple eggs, which are then retrieved and fertilized with sperm in a laboratory. The resulting embryo is then transferred to the uterus, where it can implant and develop into a healthy pregnancy. IVF bypasses the need for natural fertilization and allows for the selection of healthy embryos for transfer.
**Why Each Wrong Option is Incorrect**

**Option C:** This option is incorrect because while IVF can be used to treat some cases of male infertility, it is not the primary indication for IVF.
**Clinical Pearl / High-Yield Fact**
IVF has become a common treatment option for infertility, with success rates ranging from 20-50% depending on individual factors such as age, egg quality, and sperm quality. It's essential to note that IVF is not a guarantee of success and may require multiple cycles before achieving a pregnancy.
