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.
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.
Artificial reproduction is the re-creation of life brought about by means other than natural ones. It is new life built by human plans and projects. Examples include artificial selection, artificial insemination, in vitro fertilization, artificial womb, artificial cloning, and kinematic replication.
Treatment may include ovulation induction, surgical interventions, artificial insemination, such as intrauterine insemination (IUI), in vitro fertilization (IVF), or the use of an egg donor or a sperm donor. In vitro fertilization is the most well known of the assisted reproductive technology procedures performed at a fertility clinic. Advanced ...
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.
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.
1. Fertilization. After the egg is fertilized by the sperm, a zygote (single diploid cell) is formed. At this stage, it should have two pronuclei, one of each derived from the egg and the sperm cell respectively and two tiny cells called polar bodies. 2. Cleavage. This begins when the zygote divides into two cells via mitosis. The division ...
Sperm or oocyte donors with in vitro fertilization and gestational carriers are sometimes used for gay couples, those with severe medical conditions which make pregnancy dangerous or precluding pregnancy, those with severe infertility or females with a non-functioning uterus.
