What ovarian stimulation is
Ovarian stimulation is the first main stage of IVF. It uses fertility hormones to encourage the ovaries to produce more than one egg in a cycle, rather than the single egg usually released each month.
In the NHS, this process is carefully monitored to make treatment as safe and effective as possible. The aim is to grow several mature eggs so they can be collected and fertilised in the laboratory.
How the treatment starts
Your fertility team will usually begin with an assessment before stimulation starts. This may include blood tests, an ultrasound scan, and a review of your medical history to decide which medicines and doses are most suitable.
Some NHS IVF protocols begin on day 2 or 3 of your menstrual cycle. You will be given instructions on when to start the injections and how to use them, often after a nurse teaching session.
The medicines used
Most NHS ovarian stimulation treatment uses daily hormone injections. These are usually gonadotrophins, which contain follicle-stimulating hormone, or FSH, and sometimes luteinising hormone, or LH.
These medicines help follicles in the ovaries grow. Follicles are the small fluid-filled sacs that contain eggs, and the fertility team adjusts the dose depending on your response.
Monitoring during stimulation
Monitoring is a key part of the NHS process. You will usually attend the clinic for blood tests and vaginal ultrasound scans every few days so the team can see how your follicles are developing.
These checks help reduce the risk of overstimulation and allow your dose to be changed if needed. They also help time the next stage of treatment accurately.
The trigger injection and egg collection
When the follicles are ready, you will be given a final “trigger” injection. This medicine helps the eggs complete their final stage of maturation before collection.
About 34 to 36 hours later, you will have egg collection, usually under sedation. A doctor uses an ultrasound-guided needle to remove the eggs from the ovaries.
What to expect on the NHS
NHS IVF pathways can vary slightly between trusts, but the overall process is similar. The treatment is closely supervised, and you should be told who to contact if you have side effects or concerns during stimulation.
Common side effects can include bloating, mood changes, breast tenderness, or mild discomfort at the injection site. Your clinic will explain when to seek urgent help, especially if you develop severe pain, swelling, or feel unwell.
