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.
The benefits of using morphokinetics in terms of improving clinical outcomes of IVF is still very unclear. [9] A meta-analysis published in 2017, supported the idea of clinical benefits of time-lapse culture with morphokinetic embryo selection in IVF, reporting reduced early pregnancy loss, higher ongoing pregnancy and higher live birth rates.

Repeated implantation failure (RIF) is the repeated failure of the embryo to implant onto the side of the uterus wall following IVF treatment. [1] Implantation happens at 6–7 days after conception and involves the embedding of the growing embryo into the mothers uterus and a connection being formed. [ 2 ]
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 ...
People who have experienced repeatedly failed implantation, or whose experimental embryo has a thick zona pellucida (covering) around the embryo, have ideal candidates for assisted zona hatching. The procedure involves creating a hole in the zona to improve the chances of normal implantation of the embryo in the uterus. [citation needed]
The endocannabinoid system plays a vital role in this synchrony in the uterus, influencing uterine receptivity, and embryo implantation. [5] The embryo expresses cannabinoid receptors early in its development that are responsive to anandamide (AEA) secreted in the uterus. AEA is produced at higher levels before implantation and is then down ...
The majority of IVF-conceived infants do not have birth defects. [13] However, some studies have suggested that assisted reproductive technology is associated with an increased risk of birth defects. [14] [15] Artificial reproductive technology is becoming more available. Early studies suggest that there could be an increased risk for medical ...
So providers of IVF services and embryo transport now fear legal repercussions if embryos are discarded — a common part of the IVF process, since some embryos can have genetic abnormalities or ...
