If a woman is having trouble conceiving after a period of time having regular unprotected sex, and infertility is diagnosed, drugs to assist fertility may be recommended.
Fertility treatments usually affect hormones involved in ovulation and may be taken as tablets or injections.
However, ovary stimulating drugs are not recommended where a woman's fertility is unexplained as these treatments are less likely to be effective in these cases.
Fertility drugs include:
Clomifene encourages the release of eggs in women who do not ovulate regularly, or who do not ovulate at all.
Tamoxifen is more well known as a breast cancer treatment, but may be recommended as an alternative to clomifene for women with ovulation problems.
Better known as a diabetes drug, metformin may help with fertility problems for women with polycystic ovary syndrome (PCOS).
Gonadotrophins, gonadotrophin-releasing hormone and dopamine agonists
These drugs help to encourage ovulation.
