There are several diseases that are more common in men than women, or that specifically affect men. Here are some examples:

1. Prostate cancer: This is a type of cancer that develops in the prostate gland, which is located in the male reproductive system.
2. Erectile dysfunction: This is a condition where a man has difficulty achieving or maintaining an erection.
3. Testicular cancer: This is a type of cancer that develops in the testicles, which are part of the male reproductive system.
4. Benign prostatic hyperplasia (BPH): This is a condition where the prostate gland becomes enlarged, causing urinary problems.
5. Male pattern baldness: This is a genetic condition that causes hair loss in men.
6. Peyronie’s disease: This is a condition where scar tissue forms inside the penis, causing a curvature or deformity.
7. 1. Hypogonadism: This is a condition where the testes produce less testosterone than normal, leading to a variety of symptoms.

   It’s important to note that while these diseases may be more common in men, they can still affect women as well.
