Ovulation triggering with GnRH agonists
Ovarian hyperstimulation syndrome (OHSS) remains a major complication of IVF. Triggering ovulation with human chorionic gonadotrophin (HCG) (as a surrogate to LH) is a major factor in the initiation of OHSS. The pathological process usually intensifies if pregnancy is achieved, as the rising endogenous HCG overstimulates the corpora lutea. Decreasing HCG trigger dose does not prevent OHSS. Gona...
متن کاملOvulation and Endocrine Response after Lh-rh in Domestic Animals
cows 2 weeks after parturition and in diestrous and proestrous heifers. Serum LH concentrations increased after LH-RH treatment and the greatest response was observed in cows with ovarian follicular cysts. Serum progesterone concentrations were increased at 6 hours after LH-RH in animals which had functional luteal tissue in the ovaries but serum estradiol and estrone were unchanged. Ovarian fo...
متن کاملOestrus, LH, ovulation and fertility in beef heifers.
The pregnancy rate resulting from matings at a single oestrus in beef cattle averages 70% for natural mating (Turman, Laster, Renbarger & Stephens, 1971) and 60% for artificial insemination (Laster, Glimp & Gregory, 1972). The sources and causes of low pregnancy rates have not been defined, but might include variation in time of ovulation relative to deposition of spermatozoa in the female repr...
متن کاملRecombinant versus urinary gonadotrophins for triggering ovulation in assisted conception.
BACKGROUND The objective of this systematic review was to assess the safety and efficacy of subcutaneous recombinant (r) HCG and high-dose rLH compared with intramuscular urinary (u) uHCG for inducing final oocyte maturation and triggering ovulation. METHODS We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (August 27, 2003), the Cochrane Central Register of ...
متن کاملHCG: Is it the Best Choice for Ovulation Triggering?
With the increasing use of gonadotropin releasing hormone antagonist protocols, it has become an option to trigger ovulation with gonadotropin releasing hormone agonist which has several advantages over human chorionic gonadotropin triggering; among those an elimination or reduction in ovarian hyperstimulation syndrome, and a reduction in luteal phase discomfort. Thus, this paper questions the ...
