Clomiphene citrate has a 6-month treatment duration as given in most of the research work. I need a chemical/drug that has a shorter treatment period (30-45 days) and the mechanism of action of that chemical should be similar to that of Nonylphenol affecting male infertility.

Kindly suggest.

Note: Nonylphenol acts as xenoestrogen usually functions by binding to estrogen receptors and acts against natural estrogens. It mimics 17 beta estradiol and it competes with the endogenous hormone for binding with the estrogen receptors ER alpha and ER beta.
