Clomiphene citrate is a medication initially used in the treatment of infertility in women. This medication when used for hormone replacement therapy in men, has been found to increase what is known as luteinizing hormone or LH. Luteinizing hormone is responsible for the production of natural testosterone. The natural aging process causes this blood level to decrease in males over the age of 25-30, resulting in erectile dysfunction and all other symptoms of low testosterone. Clomiphene, when taken correctly as directed by your physician, increases one’s luteinizing hormone (LH) levels, resulting in elevated testosterone levels as a potential alternative for testosterone injections.
