assisted reproductive technology

(redirected from Assisted reproductive technique)


scientific knowledge; the sum of the study of a technique.
assisted reproductive technology (ART) any procedure that involves manipulation of eggs or sperm to establish pregnancy in treatment of infertility, such as in vitro fertilization, gamete intrafallopian transfer, tubal embryo transfer, and zygote intrafallopian transfer.

as·sist·ed re·pro·duc·tive tech·nol·o·gy

originally, a range of techniques for manipulating oocytes and sperm to overcome infertility; encompasses drug treatments to stimulate ovulation, surgical methods for removing oocytes (for example, laparoscopy and ultrasound-guided transvaginal aspiration) and for implanting embryos (for example, zygote intrafallopian transfer or ZIFT), in vitro and in vivo fertilization (for example, artificial insemination and gamete intrafallopian transfer or GIFT), ex utero and in utero fetal surgery, and laboratory regimes for freezing and screening sperm and embryos as well as micromanipulating and cloning embryos as well as See: eugenics.

assisted reproductive technology

Any of various techniques for enhancing fertility, such as in vitro fertilization, in which both the egg and the sperm are manipulated.

assisted reproductive technology

The range of technologies used in the treatment of infertility. These include in vitro fertilization, the use of frozen embryos, embryo screening, testicular sperm retrieval, sperm microinjection, chromosome screening, frozen ova and long-frozen sperms from dead donors.

Some of these factors as per the Market Research Future (MRFR) report include declining rate of fertility, increasing number of fertility clinics, advancements in technology, increasing grants, funds and public-private investments, lifestyle disorders, increasing awareness about infertility, accessibility of advanced infertility treatment devices and treatment option and advent of various assisted reproductive techniques. On the contrary, factors such as complications and risk related to infertility treatment, soaring procedural cost, unsupportive government regulations, poor efficacy of infertility treatment, social taboos concerning the treatment and side effects of drug therapy is likely to act as major barriers in the infertility market growth.
Madam, male infertility affects 15% of couples which is equivalent to 48.5 million couples globally.1 Genetic tests for the diagnosis of cause of infertility have been used to develop guide lines to inform risk of transmission of genetic characteristics while electing for assisted reproduction.2 Study done by Atif et al documented that routine screening for Y chromosome microdeletion is important for proper genetic counseling because this can presumably be transmitted as a fertility problem to their sons.3 It is, therefore, very important to offer proper genetic counseling to the infertile couples particularly those who wish to undergo assisted reproductive techniques.
