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 ]
Following feature extraction, ERICA accurately ranks embryos according to their prognosis (defined as euploidy and implantation potential). In this way, ERICA removes the subjectivity inherent to previously existing classifications and, by efficiently assisting clinicians, increases the chances of selecting the one embryo with the best chances ...
In terms of insemination, ICSI needs only one sperm cell per oocyte, while IVF needs 50,000–100,000. This is because the acrosome reaction has to take place and thousands of sperm cells have to be involved in IVF. Once fertilized, the egg is transformed into a pre-embryo and it has to be transferred to the uterus to continue its development.
Theriogenology is a specialty of veterinary medicine concerned with animal reproduction. This includes the physiology and pathology of male and female reproductive systems of animals and the clinical practice of veterinary obstetrics, gynecology, andrology and assisted reproductive technologies (ART).
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 ...
"Female embryos were selectively transferred in five couples at risk of X-linked disease, resulting in two twin and one singleton pregnancy." [3] [4] The term preimplantation genetic screening (PGS) refers to the set of techniques for testing whether embryos (obtained through IVF/ ICSI have an abnormal number of chromosomes . PGS is also called ...
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.
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and cryopreservation of gametes and embryos, and the use of fertility medication.
