Step 1: Assisted Reproductive Technologies (ART) are medical procedures used to help individuals and couples conceive. These technologies are used in cases of infertility or genetic conditions.
Step 2: Some of the key ART methods include:
1. In Vitro Fertilization (IVF): This process involves fertilizing an egg outside the body and then implanting the embryo into the uterus.
2. Intracytoplasmic Sperm Injection (ICSI): A single sperm is directly injected into an egg to facilitate fertilization, used in cases of male infertility.
3. Intrauterine Insemination (IUI): Sperm is directly inserted into the uterus to increase the chances of fertilization.
4. Egg/Sperm Donation: Donated eggs or sperm are used in cases where one partner has infertility issues.
5. Surrogacy: A woman carries and gives birth to a child for another individual or couple.
Step 3: ART has enabled many individuals and couples to overcome infertility and has become an essential part of reproductive medicine.
