In vitro maturation (IVM) is the technique of letting the contents of ovarian follicles and the oocytes inside mature in vitro.It can be offered to women with infertility problems, combined with In Vitro Fertilization (IVF), offering women pregnancy without ovarian stimulation.
Women starting at around age 42 to 45 are typically advised not to proceed with IVF with their own eggs because older eggs have a higher chance of abnormalities. Gene variant protects against ...
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.
A physician may use a transvaginal ultrasound to visualize and count the number of antral follicles in each of a woman's ovaries in order to determine her ovarian reserve; however AFC is not predictive of embryo quality. [12] A higher number of antral follicles indicates a higher likelihood of pregnancy by IVF.
In IVF, final maturation induction is preceded by controlled ovarian hyperstimulation. It is suggested that there should be a size of ovarian follicles of at least 15 mm, and serum estradiol level of 0.49 nmol/L before commencing final maturation induction.
A rising number of single women are embarking on parenthood without a partner, figures suggest. Some 6% of in-vitro fertilisation (IVF) cycles in 2022 were for single women, a rise from 2% in 2012 ...
Controlled ovarian hyperstimulation, which is generally part of in vitro fertilization, and the aim is generally to develop multiple follicles (optimally between 11 and 14 antral follicles measuring 2–8 mm in diameter), [medical citation needed] followed by transvaginal oocyte retrieval, co-incubation, followed by embryo transfer of a maximum ...
These multiple follicles can be taken out by oocyte retrieval (egg collection) for use in in vitro fertilisation (IVF), or be given time to ovulate, resulting in superovulation which is the ovulation of a larger-than-normal number of eggs, [2] generally in the sense of at least two.
