Association between occupational testicular radiation exposure and lower male sex ratio of offspring among orthopedic surgeons.

ABSTRACT:

Background

Exposure to occupational radiation can lower the male sex ratio. However, specific radiation exposure to the testes has not been evaluated.

Objective

This study aimed to examine the association between testicular radiation exposure and lower male sex ratio in children.

Methods

A comprehensive questionnaire survey was administered to 62 full-time male doctors with children aged < 10 years at 5 hospitals. Based on the possibility of testicular radiation exposure 1 year before the child's birth, participants were assigned to 3 groups as follows: RT (orthopedic surgery), RNT (cardiology/neurosurgery), and N (others).
