Final answer:
Untreated STDs can sometimes lead to infertility due to reproductive complications caused by the diseases.
Step-by-step explanation:
True. Untreated sexually transmitted diseases (STDs) can lead to infertility in some cases. STDs, such as chlamydia and gonorrhea, can cause pelvic inflammatory disease (PID) in women, which can result in scarring of the fallopian tubes and other reproductive complications. In men, untreated STDs can lead to epididymitis, which can affect sperm production and mobility. It is important to seek timely treatment for STDs to prevent potential long-term consequences.
