Conclusions
-
1.
Surfagon, an analog of luliberin, possesses high biological activity, surpassing the biological activity of luliberin by a factor of 10 in the test of stimulation of secretion of gonadotropins by the rat pituitary in vivo and in the test of induction of ovulation in rats.
-
2.
Surfagon has a prolonged effect on the secretion of gonadotropins in vivo and in vitro.
-
3.
The use of various doses of surfagon permits selective stimulation of secretion only of LH or of LH and FSH by the pituitary in rats.
