In vitro fertilization (IVF) is a process of fertilization 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.
However, whether insemination takes place naturally or by artificial means, the pregnancy and the progress of it will be the same. Insemination may be called in vivo fertilisation (from in vivo meaning "within the living") because an egg is fertilized inside the body, this is in contrast with in vitro fertilisation (IVF).
In vitro fertilization: once the egg is obtained it is fertilized with the donor sperm in a laboratory. [7] This can be done by ICSI technique or regular In vitro fertilization. Once the egg is fertilized, embryos are obtained that are kept in the lab for 3 to 5 days, when they develop to blastocysts. [ 8 ]
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 ...
Embryo transfer is the step in the process whereby one or several embryos are placed into the uterus of the female with the intent to establish a pregnancy. Less commonly used techniques in in vitro fertilization are: Assisted zona hatching (AZH) is performed shortly before the embryo is transferred to the uterus. A small opening is made in the ...
With the 8 couples with embryo cryopreservation, there was a 65% fertilisation rate. At least one good quality day 3 embryo was cryopreserved in 7/8 couples. This experiment shows that IVM of oocytes obtained ex vivo during the processing of ovarian cortex prior to cryopreservation is a promising solution for patients at risk for fertility loss ...
The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. [1] [2] The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge.
