A meta-analysis came to the result that the optimal daily recombinant FSH stimulation dose is 150 IU/day in presumed normal responders younger than 39 years undergoing IVF. [15] Compared with higher doses, this dose is associated with a slightly lower oocyte yield, but similar pregnancy rates and embryo cryopreservation rates. [ 15 ]
The risk is further increased by multiple doses of hCG after ovulation and if the procedure results in pregnancy. [2] Using a GnRH agonist instead of hCG for inducing final oocyte maturation and/or release results in an elimination of the risk of ovarian hyperstimulation syndrome, but a slight decrease of the delivery rate of approximately 6%.

Transvaginal oocyte retrieval (TVOR), also referred to as oocyte retrieval (OCR), is a technique used in in vitro fertilization (IVF) in order to remove oocytes from an ovary, enabling fertilization outside the body. [1]
Risks associated with the egg collection procedure relate to bleeding and infection. The collection procedure involves passing a needle through the wall of the vagina into vascular-stimulated ovaries. A small amount of bleeding is inevitable. In rare cases, there is excessive bleeding into the abdomen requiring surgery.
In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
Freezing embryos for IVF became standard practice after the development of vitrification, a fast-freezing process that is safer for the embryo. While there’s still a risk of damage during the ...
Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures: IVF without the use any ovarian hyperstimulation drugs. [1] IVF using an ovarian hyperstimulation protocol with a GnRH antagonist for ovulation suppression, generally with gonadotropins as well. [2] This procedure can be called modified natural cycle-IVF ...
IVF procedures were temporarily halted, shocking people who were trying to become parents and injecting an emotionally sensitive issue into the national debate over reproductive rights.
