Ovulation induction (OI)
Ovulation induction (OI)
Ovulation induction is a simple treatment that uses medication to stimulate the ovaries and encourage ovulation. No injections, and you still have sex to become pregnant.
Clomiphene treatment
Clomiphene citrate was the original ‘fertility pill’. It is still widely used and is 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:
• those who don’t ovulate or who have irregular cycles, and
• those with a shorter duration of unexplained infertility.
Letrozole treatment
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.
