State the pharmacological effects of hormonal contraceptives for men.

Hormonal contraceptives for men, such as testosterone-based injections or implants, work by suppressing the production of sperm in the testes. This leads to a decrease in sperm count and motility, making it less likely for a man to impregnate a woman. Additionally, hormonal contraceptives can also affect the production of other hormones in the body, such as testosterone, which can lead to changes in libido, mood, and muscle mass.

Hormonal contraceptives for men are still in the experimental stage of development and have not yet been approved for clinical use. Therefore, there are no pharmacological effects of hormonal contraceptives for men that can be stated at this time.
