Hi there I understand your concern...you do have chance if no other abnormalities associated..Need detailed history about age at marriage, associated medical history...first thing you should know is- infertility means unable to concieve even after one year of unprotected regular Sex. If that's the case it may be due to numerous causes, in womens- it might be due to uterine abnormality,hormonal imbalance, fibroid in uterus,sometimes infection like T.B would have scarred fallopian tube which might be a cause,certain medications, obesity etc...I would suggest you to post all available reports here with history we would surely help you..

Absolutely if you address any underlying  hormone  imbalances.

Ovarian Reserve decreased after 35 and drastically after 37. If require go for IUI/IVF . Dont delay. Age is MAJOR rate limiting factor in test tube baby.
