Clomiphene Citrate was the original ‘fertility pill’, and it is still widely used. It’s the most ‘natural’ scientifically proven fertility treatment – no injections, and you still have sex to become pregnant.
Clomiphene is mainly used for two groups of people:
- Women who don’t ovulate or who have irregular cycles.
- Women with a shorter duration of unexplained infertility.
Letrozole is a new alternative for women who don’t ovulate or have irregular cycles. Overall, about 20-30% of women aged 37 and under have a child over a course of up to 3-4 cycles of Clomiphene or Letrozole.
There is a slightly increased chance of twins, which can be reduced to around 5–10% by checking the body’s response to the medication using a blood test or an ultrasound scan.
