This PoOO hypothesis, therefore, is more plausible than that of James (22,23), who assumes that the high gonadotropin and low testosterone levels would have injured and skewed the Y-bearing gametes before conception.
1) speculated on the value of development of a specific assay to measure human luteinizing hormone [beta]-core fragment (hLH[beta]cf) without cross-reactivity with human chorionic gonadotropin [beta]-core fragment (hCG[beta]cf).
Of particular interest to the researchers was the gonadotropin called follicle-stimulating hormone (FSH).
The hormonal treatment market for CPP involves the administration of synthetic GnRH agonists such as Supprelin(R) (histrelin acetate) and Lupron Depot-Ped(R) (leuprolide acetate for depot suspension) which inhibit pituitary release of gonadotropins, and can block both ovarian and testicular function.
Indeed, although twins resulted from as many as 29% of successful inseminations in the low-dose studies, no higher-order multiples were reported in 1,123 cycles, When higher doses of gonadotropins were used, as many as 9.
Experimental studies have demonstrated decreases in gonadotropins, sperm production, follicular development, ovulation and conception after immunization against GnRH, chemically conjugated to a carrier protein.
MENOPUR, like all gonadotropins, is a potent substance capable of causing mild to severe reactions, including OHSS (overall incidence of 3.
MENOPUR(R), like all gonadotropins, is a potent substance capable of causing mild to severe adverse reactions, including ovarian hyperstimulation syndrome (OHSS) (incidence of 3.
The study was not blinded but randomized patients by "concealment of allocation" to either a standard protocol of gonadotropins or letrozole before IVF.
4) The goal of the stimulation with exogenous gonadotropins, combined with the administration of gonadoliberin analogs (GnRHa) in patients undergoing in vitro fertilization and embryo transfer (IVF-ET), either with clomiphene citrate or with gonadotropins alone, is to induce the ovaries to produce multiple retrievable oocytes to raise pregnancy rates [1-141.
The LHRH agonist, a Roberts therapeutic, is a synthetic gonadotropic hormone releasing factor agonist that, due to its long-term inhibition of pituitary release of gonadotropins, can block both ovarian and testicular function.
