In Vitro Fertilization (IVF) is a Medically Assisted Reproduction technique that can be performed with gametes from both partners or using gametes (oocytes and/or sperm) donated by third parties.

In some cases, especially in cases of male-related infertility, Intracytoplasmic Sperm Microinjection (ICSI) can be used, a technique in which the sperm is selected and injected directly into the oocyte.
