Ovarian Stimulation


In a natural cycle just a single egg is usually produced, but IVF is more successful if two embryos are transferred. To achieve this drugs are given by injection to stimulate more follicles (fluid filled spaces in the ovary which contain an egg) to produce eggs. The drugs are tailored to each patients needs.

Before ovarian stimulation can start, down-regulation is carried out to prevent premature ovulation and to aid cycle management. This requires either injections or nasal spray.


Informed consent from both partners is required before stimulation. The consent forms, which are a legal requirement, will be discussed in full with a consultant or nurse during the monitoring period.
