Will small testicles, small penis, and premature ejaculation affect fertility?

Patient's question:

At 14, I finally realized I was different from others

Doctor's answer:

Hello, considering your situation, it is likely premature ejaculation. As long as there are normal sperm, pregnancy is possible.
Advice: It is recommended to take Liuwei Dihuang Wan and Gushi Suojing Wan to treat it. Exercise can also help. During treatment, it is best to avoid frequent sexual activity.
