According to the Cochrane review on ovarian stimulation protocols for IUI in the women with subfertility, use of gonadotropins
for COS in IUI results in higher pregnancy rate than clomiphene citrate stimulated cycles.
releasing hormone agonist instillation into the uterine cavity before embryo transfer is not recommended to increase implantation and pregnancy rate in in vitro fertilization.
IUI and gonadotropin
stimulation therefore may not be an optimal treatment strategy directed at the cause of infertility, yielding lower pregnancy rates.
Although higher doses of agonists for the final oocyte maturation have a potential to result in higher gonadotropin
surge amplitude and improve the oocyte quantity, the mean number of retrieved oocytes varies and no clear benefit has been demonstrated by this approach (18).
GNRHR plays a pivotal role in normal gonadotropins
secretion during puberty (Beate et al.
In all the 4 groups, the gonadotropin
administration was continued up to the day of human chorionic gonadotropin
injection (hCG) (Gonasi[R] HP, IBSA Italia, Rome, Italy).
Patients in the flare-up protocol were started on 50 [micro]g SC of leuprolide acetate (Lucrin; Abbott, Cedex, France) twice daily on cycle day (CD) 2 followed by high dose gonadotropin
stimulation on CD 3.
The role of TRH-stimulated prolactin responses in distinguishing gonadotropin
deficiency from constitutional delayed puberty.
A blunted response is obtained in the gonadotropin
releasing hormone test.
A radioimmunoassay which specifically measures human chorionic gonadotropin
in the presence of human luteinizing hormone.
Considered to be one of the biggest breakthroughs in the treatment of infertility in the last 10 years, Elonva will allow patients to take a single injection of Corifollitropin Alfa, over the course of a week, rather than the daily injection of gonadotropin
, traditionally prescribed, said experts at the launch event held at the Marina Hotel in Kuwait.
Microscopic examination of pituitary adenoma specimens shows many gonadotropin
cells with small secretory granules and, immunohistochemical examination shows pituitary gonadotropic hormone antibody positivity.
