ICSI sperm injection into oocyte. Oocyte cryopreservation is a procedure to preserve a woman's eggs ().The technique is often used to delay pregnancy.At the time pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos.
Injection of hCG as a trigger for ovulation confers a risk of ovarian hyperstimulation syndrome, especially in patients with polycystic ovary syndrome who have been hyperstimulated during previous assisted reproduction cycles. [12] Complications of TVOR include injury to pelvic organs, hemorrhage, and infection.
A transvaginal oocyte retrieval is then performed at a time usually between 34 and 36 hours after hCG injection, that is, shortly before when the follicles would rupture. A retrieval at 36 hours after final maturation induction appears to result in optimal embryo quality and pregnancy outcomes. [ 9 ]
Intracytoplasmic sperm injection (ICSI / ˈ ɪ k s i / IK-see) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg. This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus.
After being inserted into the egg, the somatic cell nucleus is reprogrammed by its host egg cell. The ovum, now containing the somatic cell's nucleus, is stimulated with a shock and will begin to divide. The egg is now viable and capable of producing an adult organism containing all necessary genetic information from just one parent.

For most people, this is not an issue — but if you do consume raw eggs, Kelli warns that you should “not eat one to two dozen raw eggs regularly, because that can cause a biotin deficiency.”
Egg donation is the process by which a woman donates eggs to enable another woman to conceive as part of an assisted reproduction treatment or for biomedical research. For assisted reproduction purposes, egg donation typically involves in vitro fertilization technology, with the eggs being fertilized in the laboratory; more rarely, unfertilized eggs may be frozen and stored for later use.
