What is in vitro maturation means?

In vitro maturation (IVM) is when a woman’s eggs are collected and matured outside the body. This is done as part of an in vitro fertilization (IVF) procedure. A woman’s eggs (also called oocytes) are formed before she is born.

What is in vitro maturation in animals?

In IVF, eggs develop and mature under the influence of gonadotrophin stimulation in vivo (inside the female body) and are retrieved already matured. During IVM, immature eggs are retrieved from nonstimulated or minimally stimulated ovaries and are then matured and fertilized in vitro (in the laboratory).

How is in vitro fertilization done in cattle?

During IVF, unfertilized eggs are harvested directly from the animal. While this process is typically used for cows and heifers, some dog breeders may also use the process. Recovered eggs are fertilized one day after they’ve been aspirated. They’re then transferred roughly one week after they’ve been fertilized.

What is in vitro embryo production?

A more recent technique is the in vitro production of embryos. In this procedure, oocytes are harvested from donor animals, matured and fertilized in vitro, and the resultant embryos are cultured in the laboratory until either transferred immediately to recipients or cryopreserved for transfer at a later date.

How is Superovulation done?

Superovulation is achieved by eliminating the inhibitory mechanism of the dominant follicle (immunization against inhibin) or by promoting development of a subordinate follicle using follicle-stimulating gonadotropins.

What is in vitro assisted fertilization in cattle?

In cattle,assisted reproductive technologies (ART) can be defined as techniques that manipulate reproductive-related events and/or structures to achieve pregnancy with the final goal of producing healthy offspring in bovine females.

What does in vitro fertilization means?

(in VEE-troh FER-tih-lih-ZAY-shun) A procedure in which eggs are removed from a woman’s ovary and combined with sperm outside the body to form embryos. The embryos are grown in the laboratory for several days and then either placed in a woman’s uterus or cryopreserved (frozen) for future use. Also called IVF.

How does superovulation work in cows?

Superovulation is the bunch of processes to have the female to produce more eggs than the normal count of its species in each estrus by gonadotropin and to increase the number of embryos. Ten or more live eggs can be collected in each estrus from appropriate superovulated cows and heifers.
