Hello Mr. Dey,
If your wife has been investigated and treated for irregular periods
and if she is regularly ovulating now, you would be assessed for the ability of natural conception based on your semenalysis. If found compatible, you would be tried for at least six cycles on natural conception assisted with ovulation induction
with proper monitoring. In case of failure (and further trial depends on the age factor of the couple also), you may be suggested advanced methods like IUI, followed by ART. Wish you good luck.
