What are the effects of male taking levonorgestrel tablets?
If a male accidentally takes a small amount of levonorgestrel tablets, it generally will not have significant effects. However, long-term use may increase estrogen activity and reduce androgen levels, potentially leading to breast development, reduced sexual function, erectile dysfunction, and premature ejaculation.
Levonorgestrel tablets are a common oral contraceptive used in daily life. They are a combined hormonal preparation containing both estrogen and progestin, designed as a long-acting contraceptive for women. The primary mechanism is to inhibit ovulation by suppressing ovarian function. When taken by males, these tablets may cause endocrine disruption, resulting not only in adverse reactions such as headaches, stomach pain, body swelling, nausea, and vomiting, but also potentially causing liver function abnormalities and increasing the risk of cardiovascular and cerebrovascular diseases. Prolonged use may lead to feminization in men, manifested as breast development, hair loss, and a higher-pitched voice.
Short-term use of progestin-containing medications typically does not cause significant harm to the male reproductive system; however, long-term use can impair male reproductive health. Therefore, men should avoid taking levonorgestrel tablets.
