There was no significant difference in most of the treatment variables between the two groups, except the total dose of gonadotropin
, which was significantly higher in GnRH antagonist group (984 vs.
releasing hormone agonist, embryo transfer, uterine cavity, in vitro fertilization
The current study was planned to analyse IUI data obtained from controlled ovarian stimulation cycles with gonadotropins
and establish the prognostic factors for positive pregnancy outcome.
Mild ovarian stimulation for IVF uses a low dosage of gonadotropins
(100-150 IU), which usually starts in the early follicular phase in combination with a GnRH antagonist five to seven days of stimulation to produce a maximum of ten oocytes.

Therefore, despite the large number of papers published on COH protocols comparing the efficiency of different exogenous gonadotropins
, no confirmed protocol exists, and it is not quite clear which is superior to the others.
In a Cochrane review (19), it was reported that the GnRHant produced higher number of oocytes and used lower dose of gonadotropins
compared with GnRHa long protocol and GnRH-a flare up protocol had an increased frequency of IVF cancellation compared with the GnRH-a long protocol.
025%), which is caused by defective gonadotropin
secretion from the anterior pituitary because of defective gonadotropin
-releasing hormone (GnRH) from the hypothalamus.
SAN FRANCISCO -- The higher the dose of gonadotropin
for ovarian stimulation, the lower the five birth rate, a retrospective study of 541,967 cycles of assisted reproductive technology showed.

Carbohydrate and peptide structure of the alpha- and beta-subunits of human chorionic gonadotropin
from normal and aberrant pregnancy and choriocarcinoma.
This has potential adverse ramifications when we consider that the initial use of gonadotropins
derived from the human pituitary was discontinued due to the iatrogenic transmission of Creutzfeld-Jakob disease.
University of New Hampshire professor of biochemistry Stacia Sower and colleagues at two Japanese universities have identified the first reproductive hormone of these gonadotropins
Researchers working in endocrinology, genetics, investigative medicine, integrative physiology, and other fields in Europe, Brazil, and the US address the biology, pathophysiology, and mutations of genes for gonadotropins
and their receptors; the processes of regulation of gonadotropin
-releasing hormone and its dysfunction; the underlying causes of central hypogonadism; and animal models.
