Ovulation will occur between 38 and 40 hours after a single HCG injection. [8] It is also used in in vitro fertilization , where it makes the follicles perform their final maturation. A transvaginal oocyte retrieval is then performed at a time usually between 34 and 36 hours after hCG injection, that is, shortly before when the follicles would ...
In ovarian hyperstimulation combined with IUI, women aged 38–39 years appear to have reasonable success during the first two cycles, with an overall live birth rate of 6.1% per cycle. [12] However, for women aged ≥40 years, the overall live birth rate is 2.0% per cycle, and there appears to be no benefit after a single cycle of COH/IUI. [12]
The trigger shot is typically administered when the dominant follicle reaches 18–20 mm. [27] The recommended timing of IUI after hCG administration is 24–40 hours. [27] IUI cycles stimulated with classical doses of FSH have a high rate of have a multiple pregnancy with rates ranging from 10 to 40%. [29]
Commonly, this is known as the "trigger shot." [52] hCG acts as an analogue of luteinising hormone, and ovulation would occur between 38 and 40 hours after a single HCG injection, [53] but the egg retrieval is performed at a time usually between 34 and 36 hours after hCG injection, that is, just prior to when the follicles would rupture. This ...

The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. [1] [2] The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge.
Natural or Mini-IVF, but without the use of hCG to trigger ovulation, instead the GnRH agonist Synarel (nafarelin acetate) in a diluted form is taken as a nasal spray to trigger ovulation. Human chorionic gonadotropin (hCG) has a long half life and may stimulate (luteinize) small follicles prematurely and cause them to become cysts.
Sperm washing is the process in which individual sperms are separated from the semen.Washed sperm is used in artificial insemination using the intrauterine insemination (IUI) technique and in in vitro fertilization (IVF).
