Optimal Timing of Intrauterine Insemination (IUI) When Utilizing Superovulation Combined With GnRH Antagonists
The timing of IUI following ovulation induction has been the subject of many studies and a consensus has developed that a single insemination approximately thirty-six hours after ovulation induction is sufficien. The introduction of GnRH antagonists preventing a premature LH surge and early ovulation has added a new dimension to fertility treatment. It allows greater accuracy in predicting the timing of ovulation and has been shown to be at least as effective, if not more effective, as ovarian stimulation without antagonists. We hypothesize that by utilizing GnRH antagonists we can increase pregnancy rates during IUI by timing the IUI as close as possible to the moment of ovulation guaranteeing the highest and freshest concentration of motile spermatozoa in the fallopian tube at the time the oocyte is released from the ovary. We therefore propose a randomized open three arm prospective trial utilizing superovulation with GnRH antagonists whereby the IUI is timed to take place 36, 42 or 48 hours after ovulation induction.

Medical and Biotech [MESH] Definitions
Insemination, Artificial, Heterologous
Human artificial insemination in which the semen used is that of a man other than the woman's husband.
Insemination, Artificial, Homologous
Human artificial insemination in which the husband's semen is used.
Intrauterine Device Expulsion
Spontaneous loss of INTRAUTERINE DEVICES from the UTERUS.
Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
Intrauterine Device Migration
The shifting in position or location of an INTRAUTERINE DEVICE from its original placement.
Our hypothesis is double insemination will improve pregnancy rates in coh cycles with more than one dominant follicles (>16mm).
The aim of this study is to assess whether GnRH agonist administration in the luteal phase improves pregnancy outcome in intrauterine insemination (IUI) cycles.
