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.
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 ...
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 ...

Embryology (from Greek ἔμβρυον, embryon, "the unborn, embryo"; and -λογία, -logia) is the branch of animal biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos and fetuses.
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 culture until the blastocyst stage confers a significant increase in live birth rate per embryo transfer, and there is no evidence of a difference between the groups in cumulative pregnancy rates. [2] Transfer day 2 instead of day 3 after fertilization has no differences in live birth rate. [3]
Natural Cycle In Vitro Fertilization (IVF) is an assisted reproductive technique designed to closely mimic a woman's natural menstrual cycle. In traditional IVF, a woman's ovaries are stimulated with fertility medications to produce multiple eggs, which are then retrieved and fertilized outside the body.
Embryo transfer: the strongest and genetically correct embryos are selected and the decided number will be transferred to the gestational carrier. [ 10 ] Pregnancy test: after two weeks, a period known as the two-week wait it can be determined if the embryos had been properly implanted and will result in a pregnancy.
