Normal hormone,normal male sperm study and normal menses: still can’t conceive then give TRY with clomiphene, that is Antagonist at GnRH receptor at Hypothalamas, Block Estrogen mediated inhibition of GnRH hence Increase release of GnRH>>>>>>inc. LH surge ovulation Bromocriptine - would be helpful if the pt has infertility due to INCREASE PROLACTIN. DES - is stopped in US due to clear cell carcinoma in young female born to mother. Ethinyl estradiol - bind estrogen recepto>>>>>inhibit GnRH >>>>no LH surge: no use (inc. Risk of endometrial carcinoma) Medroxyprgestroene - is progestrin —-bind progesterone receptor....is(component of morning after pill)

Normal hormonal, male sperm study and normal semen: still can’t conceive then give TYR (???) with clomiphene, that is antagonist at GnRH receptor at hypothalamus, block estrogen mediated inhibition of GnRH hence increase release of LH surge Bromocriptine - would be helpful if the pt has infertility due to INCREASE LPEDS CTIRAON (??? I am assuming its PROLACTIN) - is stopped in US due to clear cell carcinoma in young female born to term. Ethinyl estradiol - bind estrogen & GnRH; LH surge: no use. (Inc risk of endometrial carcinoma) Medroxyprogesterone - is progesterin bind progesterone eonis(oeeccn.rprpmot..t. (???) of morning after pill)
