Abdominal testicular vessel distribution in human fetuses - basis for fowler-Stephens surgery.

Purpose: To analyze the histology and distribution of abdominal testicular vessels in human fetuses Patients and Methods: We studied 19 fetuses (34 testes) ranging in age from 12 to 19 weeks post-conception. The fetuses were evaluated regarding crown-rump length (CRL), total length (TL) and body weight immediately before dissection. Each testis was dissected and embedded in paraffin, from which 5 μm thick sections were obtained and stained with Masson's trichrome and Anti-CD31 antibody to quantify the vessels.
