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.
In a study, in which thirteen authors from nine different research centers and ART clinics form France, Israel and Spain participated and brought together a set of 9012 in vitro fertilization (IVF) attempts made in cases of male infertility, 3339 (37.1%) using conventional ICSI and 5673 (62.9%) performed using the IMSE technique.
In practice, it is generally calculated as the number of intrauterine gestational sacs observed by transvaginal ultrasonography divided by the number of transferred embryos. [2] As an example, one center in the United States reported an implantation rate in IVF of 37% at a maternal age of less than 35 years, 30% at 35 to 37 years, 22% at 38 to ...
Intracytoplasmic sperm injection (ICSI / ˈ ɪ k s i / IK-see) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg. This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus.
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.
Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures: IVF without the use any ovarian hyperstimulation drugs. [1] IVF using an ovarian hyperstimulation protocol with a GnRH antagonist for ovulation suppression, generally with gonadotropins as well. [2] This procedure can be called modified natural cycle-IVF ...
Sir Robert Geoffrey Edwards (27 September 1925 – 10 April 2013) was a British physiologist and pioneer in reproductive medicine, and in-vitro fertilisation (IVF) in particular. Along with obstetrician and gynaecologist Patrick Steptoe [ 7 ] and nurse and embryologist Jean Purdy , Edwards successfully pioneered conception through IVF, which ...
Since only embryos of the desired sex are transferred to the mother, IVF/PGD avoids the small likelihood present in the Ericsson method of an undesired sperm fertilizing the egg. Sex selection success rates for IVF/PGD are very high. The technique is recommended for couples who will not accept a child of the undesired sex. [26] [27]
