It is used in instances where the fertility problem relates to sperm dysfunction, and where the couple has idiopathic (unknown cause) infertility. Some patients may prefer the procedure to IVF for ethical reasons, since the fertilization takes place inside the body. [4] This is a semi invasive procedure and requires laparoscopy.
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.
Transvaginal oocyte retrieval is more properly referred to as transvaginal ovum retrieval when the oocytes have matured into ova, as is normally the case in IVF. It can be also performed for egg donation, oocyte cryopreservation and other assisted reproduction technology such as ICSI.
The number of eggs is a large part of how IVF overcomes infertility, she added. Even in a young, healthy patient, about 30% to 50% of the eggs won’t develop into a pregnancy, Chen said.
Autologous Endometrial Coculture is a technique of assisted reproductive technology.It involves placing a patient’s fertilized eggs on top of a layer of cells from her own uterine lining, creating a more natural environment for embryo development and maximizing the chance for an in vitro fertilization (IVF) pregnancy.

After the egg is fertilized by the sperm, a zygote (single diploid cell) is formed. At this stage, it should have two pronuclei, one of each derived from the egg and the sperm cell respectively and two tiny cells called polar bodies. 2. Cleavage. This begins when the zygote divides into two cells via mitosis. The division continues such that ...
