Inducing ovulation
Women in a normal cycle liberate an ovum (ovocyte) 14 days after their menstruation. In the assisted reproduction technique they recommend a controlled ovum stimulation, which aims to provoke the development of various ovary follicles to produce a greater amount of mature ovums, thus increasing the chances for success in each cycle.
Ovulation induction is done with hormones (FSH and LH) which are very similar to those produced by women, at more than normal dosage. There are a variety of medication guidelines, and the selection of the proper guideline is based on the couple's clinical history and the type of assisted reproduction chosen by the medical team. Within a single treatment cycle the medical dosage can change from one day to another depending on the ovary's response. This ovarian response is determined through the quantification of estradiol (female hormone) which is measured in the blood, and the level of ovarian follicles seen through a vaginal ultrasound. These studies are done on specific days of the menstrual cycle and called follicle follow-up. When there are an adequate number of mature follicles the assisted reproduction technique is carried out.
Between 1 and 2% of the patients have an exaggerated response to the medication (ovarian hyperstimulation syndrome). Complications of ovarian hyperstimulation may be seen through abdominal pain, dizziness, shortness of breath and bloating in lower limbs; there have also been cases of intense abdominal pain. However, with ultrasound tests and the routine dosage of the medication, the risk of ovarian hyperstimulation is reduced. When any signs of complications are suspected, the treatment cycle is suspended. |
