A total number of 1000 genital tracts were examined for utero-ovarian disorders. Out of which 115 genitalia showed one or more lesions in the ovary, oviduct and uterus. Among these 84 cases showed lesions in the ovaries. The follicular cyst was the most common condition and was recorded in 29 cases (2.9%). The other conditions encountered were luteal cyst (0.3 %), cystic corpus luteum (0.3%), embedded corpus luteum (1.2 %), persistent corpus luteum (0.1 %), ovarian haematoma (0.2 %), ovarian sclerosis(0.2 %), senile atrophy(0.5 %), follicular atresia (0.2 %), epoophoron (0.1 %), serous inclusion cyst (0.1 %), par ovarian cyst (2.2 %) and perioophoritis(0.1 %). Seven cases showed lesions in the oviduct. The conditions encountered were hydrosalpinx (0.1 %) and hyperplasia of the salpingeal epithelium (0.3 %).Uterine disorders recorded in 24 cases. The conditions encountered were endometrial hyperplasia (0.2%), adenomyosis (0.3 %), mucometra (0.1 %), perimetrial cyst (0.1%), serous vascular protrusions (0.5 %), endometritis (1.1 %) and metritis (0.1%). The histopathological changes of all these conditions have been studied in detail and the possible pathogenesis described. The various pathological changes associated with reproductive disorders are suggestive of endocrine imbalances, multiple nutritional deficiencies, infectious origin, managemental factors and developmental defects. The results of the study also highlight the need to monitor the hormonal levels in the blood, micronutrients and managemental factors.
