MORPHOGENESIS OF HUMAN TESTES AT DIFFERENT AGE GROUPS

Dr. N. Sreekantha Rao

Abstract :

The testes are primary reproductive organs or gonads in males, which are responsible for production of testosterone and secondary sexual characters.

Aims & Objectives:The present study is done to observe morphology and morphometric parameters at different ages.

Materials & Methods:A total number of 64 testes of pre and post natal age groups from 17 male foetal cadavers, 6 autopsies of Forensic department, One cadaver of Anatomy department, 16 from pathology department. The prenatal specimens were collected from aborted emyos and dead foetuses of 6–40 weeks gestation. The postnatal testes were collected from individuals of 9–78 years of age. Crown–rump length (CRL) and crown–heel length (CHL) of the foetuses were measured in millimetres and weight of the foetuses was recorded in grams.

Results:The emyos of 6–10 weeks post conceptional age gonads 3 were observed in lumbar level. In the foetuses of 13–28 weeks gestation 2 were abdominal (33.33%) and 4 were inguinal canal (66.66%). The percentage of inguinal canal location is very high. In the 29–40 weeks gestational ages 18 were intra scrotal (81.81%) and 4 specimens were at the neck of scrotum (18.18%). The incidence of undescended testes is 3.33%. There is gradual increase in length, width and thickness with a slightly more values on right side when compared to left side. The left testes are heavier than right testes.

Conclusion:The incidence of inguinal canal location in 2nd trimester and at the neck of scrotum in 3rd trimester is higher in prenatal age group. The incidence of undescended observed in the post natal age group is also higher in the present study.
