Ovarian stimulation
Ovarian stimulation
One of the most effective fertility treatments is ovarian stimulation, used either to treat ovulation disorders or to increase the chances of successful assisted reproduction.
When used alone, it is administered to regulate or induce monoovulation (ovulation of a single egg), restoring natural fertility.
In the case of in vitro fertilization, the goal is to obtain more mature eggs, respectively more embryos and to allow the selection of viable embryos.
When is ovarian stimulation recommended?
- Ovulation or hormonal dysfunction
- Unidentified infertility
- In association with assisted reproduction techniques
What are the risks?
- Multiple pregnancy (twins or triplets)
- Ovarian cysts – usually functional, disappear spontaneously
Medication side effects:
- Headache
- Abdominal discomfort, bloating
- Discomfort at the injection site,
- Alergic reactions
- Nausea
Other risks that cannot be excluded:
- Extrauterine pregnancy, miscarriage or other complications of pregnancy
- Ovarian hyperstimulation syndrome – rarely occurs outside of IVF

Can hormone treatment have long-term risks?
