Hello. please could you tell me which type of physician i would need to talk to regarding man and woman's fertility issues. thanks?

Fertility specialist: Once a couple is married, settled down, and has decided to start a family (these are all major decisions), they can stop using birth control methods. The wife can track her periods to see when she is most fertile. Meanwhile, she can take prenatal vitamins, stop any habits such as smoking, and be sure enjoy sex quite often. It can take up to 9-12 months for normal couples to get pregnant.
