Patient's question:
Recently, I started living with my girlfriend, and we don't use condoms during sex. Every time, my girlfriend takes birth control pills. But the other day, out of curiosity, I took a birth control pill before having sex. I heard it can kill sperm, but later I heard that men who take birth control pills can develop a woman's voice. I'm really scared.Doctor's answer:
Hello! Generally, there is no significant impact. Since most birth control pills contain either estrogen or progestogen, and men do not have progestogen receptors, the progestogen is metabolized as a foreign substance. Estrogen can only cause temporary changes because it is not used long-term, so there is little effect. If you accidentally take it once, you probably won't notice any significant changes. If men take it, their estrogen levels will increase, leading to the development of female sexual characteristics, while their male sexual characteristics will decrease. If the dosage is too high, it can cause gynecomastia (breast development in men), penis shrinkage, and reduced sexual function. Be cautious!
