Does ureaplasma urealyticum infection in men affect fertility?

Patient's question:

I was diagnosed with ureaplasma infection a few weeks ago. Will it affect fertility?

Doctor's answer:

Hello, yes. Ureaplasma infection has also become one of the highly prevalent viral infections among men in recent years. Patients often experience urethral discomfort, varying degrees of urgency and frequency in urination, and other symptoms such as painful urination. Ureaplasma interferes with sperm motility. Sperm motility is a crucial function of healthy sperm and an important indicator of whether sperm can fertilize. Moreover, sperm movement must maintain a certain speed and frequency. After infecting sperm, Ureaplasma often attaches to the head and tail of the sperm, covering the entire sperm with varying-sized attachments. This weakens the sperm's ability to swim, causing them to tangle together, leading to infertility.
