Other variables not related in order to eggs top quality can also give up fertility in the women. Which have a history of certain sexually transmitted infections, for example chlamydia or gonorrhea, can result in blocked fallopian tubes or tubal scratch that will circumvent fertility in women, Byron notes. That is why it is important to use condoms or limit the number from sexual partners, professionals say.
