[Ultrasonic follow-up of ovarian follicles in sterile women].

The authors examined 39 women with sterility varying in time. Their ovaries were follow-up during 68 menstrual cycles. Linear growth of the follicle, which detached the egg cell, was established. The size of the follicle varied between 15.4-21.4 mm during the separation of the egg cell. The follicles remained static in anovulation, after which they became regressive or formed follicular cyst with various measures.
