What may happen when clomiphene is co-administered with methyldopa to promote ovulation?

It may result to infertility or impaired fertility.

Explanation:

Infertility can be described to occur when after a year of consistent unprotected sexual intercourse of a couple, they are still unable achieve pregnancy. This is what likely to occur when the two drugs mentioned are administered at the same time during ovulation.

Note that, there is another thing referred to as impaired fecundity, which is when a woman is having difficulty in carrying a pregnancy up until the time of delivery, and can be a woman having difficulty in getting pregnant.
