Types of ovarian tumours seen in Benin-City, Nigeria
1Department of Obstetrics and Gynaecology, University of Maiduguri Teaching Hospital, Nigeria.
Abstract:
There were 243 histologically proven ovarian tumours seen at the University of Benin Teaching Hospital, Benin-City, from 1973 to 1987. Out of these 198 (81%) were benign, with dermoid cyst (31%) being the commonest benign ovarian tumour. Granulosa cell tumours was the commonest malignant ovarian tumour seen (20% of malignant cases).

01:26Ovaries
The ovaries are roughly the size of almonds and measure approximately 2 to 3 centimeters in length. These paired structures are situated within the pelvic region and are anchored by the mesovarium—a peritoneal extension that also connects them to the wider structure of the broad ligament. The support system extends to the suspensory ligament, housing blood and lymphatic vessels. In addition, the ovarian ligament tethers the ovaries to the uterus.

02:07Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
