Yes, clomiphene (clomiphene citrate) can help treat infertility, especially in women who do not ovulate regularly.
Clomiphene works by stimulating the brain to release hormones (FSH and LH) that encourage the ovaries to produce and release an egg. It is commonly used in women with conditions such as PCOS or unexplained ovulatory problems. Treatment is usually started early in the menstrual cycle and monitored by a fertility specialist to reduce the risk of multiple pregnancy and ensure the best chance of conception. It is effective only in selected cases, so the underlying cause of infertility should be evaluated before starting treatment.
Clomiphene can definitely be used for infertility, particularly when the issue is ovulation, because it helps stimulate the ovaries to release an egg. But whether it actually improves your chances depends a lot on why you're having trouble conceiving in the first place. With my own adenomyosis journey, I learnt that treating one part of the fertility picture doesn't necessarily address everything going on, so I'd want to know what your doctor is hoping clomiphene will achieve in your particular case before starting it.
