Does chlamydia make men and women infertile?
It is estimated that 10% - 40% of women who catch chlamydia develop pelvic inflammatory disease (PID) as a result. PID can affect the womb, ovaries or the fallopian tubes. If the inflammation persists over a long period of time, it can cause scarring and block the fallopian tubes. If your fallopian tubes are blocked, sperm won’t get to an egg, which means that you can become infertile. This means, that chlamydia can cause infertility if it causes PID.
It is not known how common it is for women to become infertile following a chlamydia infection but some scientists estimate that chlamydia is responsible for as many as one in five cases of infertility in women.
However, chlamydia does not only affect female fertility, it can also take a toll on male fertility. It can lead to a lower sperm count and have a negative impact on the quality of the sperm. It also increases your risk of an inflammation called epididymitis (which affects the tube that carries sperm), which can lead to scarring and result in infertility.
