Which of the following is a treatment option for male infertility associated with low sperm count?

The treatment option involving medications and lifestyle changes is appropriate for addressing male infertility associated with low sperm count, also known as oligospermia. This can include hormone therapy, such as gonadotropins, to stimulate sperm production, or medications to address any underlying endocrine issues. Additionally, lifestyle modifications, including weight management, smoking cessation, and reducing alcohol consumption, can significantly impact sperm production and overall fertility.

Other treatment options such as pelvic inflammatory disease management, radical prostatectomy, and hysterectomy are not applicable to male infertility. Pelvic inflammatory disease is a condition primarily affecting females, and while radical prostatectomy is a surgical procedure for prostate cancer, it can adversely affect fertility due to the removal of the prostate gland. Hysterectomy, being a surgical procedure to remove the uterus, is irrelevant in the context of male infertility. Therefore, focusing on medications and lifestyle changes directly targets the factors contributing to low sperm count.
