Other Complications Associated With Artificial Fertilization

poor responders, GnRH antagonist, Conventional protocol

40 patients attending IVF center during 2013 &2014 were fulfilling criteria of poor response and they failed to go through OPU as they gave \<3 mature follicles on a dose of 300U GN or more. All patients were revised for history, examinations and investigations, including age, type and duration of infertility, day 3 FSH, Day 3 E2, AMH, AFC.

40 patients attending IVF center during 2013 &2014 were fulfilling criteria of poor response and they failed to go through OPU as they gave \<3 mature follicles on a dose of 300U GN or more. All patients were revised for history, examinations and investigations, including age, type and duration of infertility, day 3 FSH, Day 3 E2, AMH, AFC All patients were 35 years old ore more We exclude patient \>44ys ,AMH \<0.3ng/ml,FSH \>13, also patients of DM, endometriosis, general disease were excluded, any local uterine anomalies were excluded. All patients received OCP for one cycle Then all had taken estradiol tablet 2 mg for one week prior to menses of the test cycle from Day 21 to day 28 Then we divide them into 2 groups US were done to exclude any cyst or follicle \>10mm First group received 300 U r FSH +150 U urinary GN from day 2 till day of HCG,dose adjusted according to the response then 0.25 cetrotide S.c was added on when leading follicle reach \>12 mm, HCG was given only if we have at least 3 mature follicles \>14 mm and the leading one \>17mm then OPU done after 36 hrs of HCG, oocytes were denuded and fertilized by ICSI to avoid low fertilization rate by conventional IVF,embryo transfer were done on day 3 when we have at least one embryo GI other wise cancelled ET, then cyclogest 800mg were given intravaginal for 14 days then quantitative BHCG done and considered positive if \> 5miu/ML 28 day after ET, TVS was done to confirm ongoing pregnancy by visualization of IU sac. Second group were received cetrotide 0.25 mg s.c alone from day 2 to day 8then we initiate GN therapy by same initial GN dose (300FSH+150U urinary GN).same adjustment of dose were done and antagonist restarted when DF \>12mm, till day of HCG, HCG,OPU, ET were done by same method and under same criteria, luteal support and follow were the same.
