Agonists are chemicals or chemical reactions that help to bind and also alter the function of activity of some type of receptor. The function of an agonist is different from that of anantagonist, which does bind receptors but does not alter the range of normal activity. The impact of an ago...
(GnRH) analogue did not show the expected increase in FSH and LH levels in MS men. Total sperm counts, motility, and percent of normal morphology were lower in MS vs. controls. Progressive MS men were found to have higher and more severe HPT axis abnormalities than relapsing MS men. ...
Effects of three different GnRH analogues in combination with two different dopamine antagonists on milt production of endangered non-spermiating male Caspian brown trout, Salmo Trutta Caspius (40) A total of 34 men underwent surgical castration and 32 men received an LHRHa. Serum samples were coll...
The patient's age, the cancer's severity and stage, the need for prompt treatment, her marital status, and her desire for future pregnancies are important considerations when choosing a fertility preservation strategy. The use of gonadotropin-releasing hormone (GnRH) agonists and the cryopreservation...
aGnRH antagonists cause immediate suppression of gonadotropin secretion. They are used after exogenous stimulation has begun and consequently shorten the total duration of treatment. A recent meta-analysis [39] reported a discreet worsening in pregnancy rates when GnRH antagonist regimens were compared to...

are called Gonadotropin Releasing Hormone (GnRH) antagonists or agonists the Advanced Fertility Center of Chicago states These medications are given subcutaneously, under the skin, until approximately 36 hours before a scheduled egg retrieval to prevent early ovulation and loss of the follicles....
but with *UNnatural* amino acidsubstitutionsat various positions in the GnRH molecule. These substitutions cause the analog to befar more potent than the original GnRH molecule.(And bear in mind the relatively newer "GnRHantagonists" are an even further modified molecule than the GnRH agonists/anal...
GnRH content of the mediobasal hypothalamus is reportedly increased following short photoperiod exposure of female hamsters [51]. These studies are consistent with central (hypothalamic) modification of type 2 deiodinase by melatonin through the ubiquitin–proteasome system. Effects of melatonin on serum ...
