We have a daughter of 8 years now we want our second child but my is not conceiving what is the reason how to make her pregnant?

Consultation time: If you have been trying for a year, both you and your partner need to consult with a fertility doc and have some basic workup done on both. If there is a problem that can be fixed they can help, if not, they can help you understand your options for assisted pregnancy.

Failure to conceive: If your wife was able to conceive the first time, she can the second. Make sure you have sex 3 times a week. Also, make sure you ovulates by doing ovulation test. If she does, she should go to obgyn to make sure her exam is normal. If no abnormalities are found, you will need to rule out your issues by doing sperm test.
