Promotion of oocyte maturation

Ovarian stimulation treatment aims to induce or improve oocyte maturation through hormone treatment or hormonal stimulation (see also under Medication). This is done with tablets or with injections, which the woman – depending on the instructions – can inject herself into the subcutaneous fatty tissue. The effect of this hormone treatment is monitored with ultrasound examinations and hormone determinations in the blood.
It can induce pregnancy even before assisted reproductive techniques are used. 

First half of the cycle (approx. 1st-14th day)

  • Follicle stimulating hormone (FSH) is the most important hormone in ovarian stimulation. It is used in all standard in-vitro fertilisation protocols. 
  • Estradiol is a sex hormone and one of the most important natural oestrogens. In the menstrual cycle, they strongly affect the uterus: They stimulate the uterine lining (endometrium) to grow and promote its blood flow.
