I want to make my partner pregnant we have sex and no pregnancy ?

Infertility??: Depends on timing and age of your partner, but if you both have kept track of her ovulation time, and have been attempting for about a year, further testing is justified: an HSG (x-ray of tubes) and a sperm exam may be helpful. If not, obtain a basal thermometer (any drug store) or an ovulation test kit to make sure it is the right time for conception to occur.
