Can secondary dysmenorrhea lead to infertility?
Generally, whether secondary dysmenorrhea leads to infertility depends on its underlying cause. Secondary dysmenorrhea caused by mild inflammation or exposure to cold usually does not result in infertility; however, if it is due to severe gynecological conditions, it may affect fertility. The detailed analysis is as follows:

If secondary dysmenorrhea results from mild pelvic inflammatory disease, cold exposure during menstruation, or improper diet, and only manifests as menstrual abdominal pain without damaging reproductive organ function or interfering with egg-sperm union and embryo implantation, symptoms can be relieved through proper regulation and will not hinder fertility.
However, if secondary dysmenorrhea is caused by conditions such as endometriosis, adenomyosis, or severe fallopian tube blockage, these diseases can directly disrupt the structural integrity of the reproductive system, impairing ovulation, fertilization, or embryo implantation. If left untreated, they may lead to infertility over time, and the dysmenorrhea symptoms often progressively worsen.
In daily life, it's important to maintain good menstrual hygiene—avoiding cold exposure, excessive fatigue, and consumption of spicy or irritating foods—to alleviate menstrual pain. If dysmenorrhea progressively worsens or is accompanied by menstrual irregularities or discomfort during intercourse, the underlying cause should be promptly diagnosed and appropriately treated. Additionally, maintaining regular sleep patterns and moderate physical activity helps preserve reproductive health.
