What are the hazards of expired condoms?

Patient's question:

No

Doctor's answer:

Generally, there is no harm. However, there have been reports abroad that excessive use of condoms can cause silicone oil to accumulate in the vagina, leading to blockage of the fallopian tubes and resulting in infertility. However, this should not be very common under normal circumstances. If we have to talk about harm, it is true that some people with sensitive constitutions may be allergic to rubber products.
