Ovulation Induction (OI)
What is Ovulation Induction (OI)?
Ovulation induction is when fertility drugs are used to induce ovulation in a woman who does not ovulate herself, to ensure a follicle develops (the follicle contains the egg). The drugs administered can be Clomiphene Citrate tablets, Letrozole tablets or FSH injections.
Who is OI suitable for?
This is the most useful treatment for women who do not ovulate.
What is involved in OI?
The dose of fertility drug required will depend on the individual, and some women may over-respond to a particular dose while others may not respond at all.
Therefore we use transvaginal scanning to close monitor the follicle development. Ovulation is likely to occur with 48 hours of the follicles reaching 18mm, so intercourse is advised over the following days.
