In Vitro Maturation (IVM) is an Assisted Reproductive Technology (ART) in which eggs are retrieved from a woman before they are matured.
The immature eggs are then artificially matured (“ripened”) in a controlled laboratory environment, usually by also adding hormones or certain proteins. Mind that IVM is typically part of an In Vitro Fertilization (IVF) procedure.
When matured, the eggs may be frozen for later use, or the eggs are manually fertilized with sperm in a dish or tube, or by using a process called Intracytoplasmic Sperm Injection (ICSI).
Afterwards, the embryos are transferred into the woman’s uterus to induce a pregnancy.
