Background: Testes develops within abdomen on the posterior abdominal wall and begin to descend down through the inguinal canal to reach the scrotum. If one or both the testes fail to descend down into the scrotal sac and lie anywhere along the pathway of descent, this condition is known as Undescended testes or Crytorchidism. This condition is significantly more prevalent in preterm, premature, SGA (small for gestational age) and LBW (low birth weight) babies. The risk for injury, and carcinoma is higher in undescended testes. Such a testis fails to produce mature spermatozoa leading to infertility. Therefore the study was done with the objectives to find the presence of any association between undescended testes and LBW, prematurity and to find any congenital anomalies associated with undescended testes. Methods: This was a dissection based study that was carried out in 100 male cadavers of the perinatal age group. Detailed particulars of the babies like age in weeks, weight and nature of death were collected from the records in the Obstretics and gynaecology department. Results: Normal descent was seen in 70 % cases and undescended testes in 30 % cases. In preterm category, undescended testes was noted in 22.5% cases with low birth weight and 10% cases with normal birth weight and in term category, 75% of the cases with normal birth weight showed normal descent. The percentage of undescended testes in LBW babies is higher (60 %) than normal birth weight babies (40%). Congenital anomalies was recorded in 6.67 % cases. Testicular anomalies was seen in 3.33% cases. Conclusions: Thus the study have shown a significant association of undescended testes with LBW and prematurity. Congenital and testicular anomalies were also recorded associated with undescended testes.
