Structural and functional Abnormalities in the Sex Organs of Male Offspring of DES-treated Mothers

Abstract:

Structural and functional abnormalities in the sex organs of male offspring of mothers treated with diethylstilbestrol (DES).

The in utero effects of DES (Diethylstilbestrol) on the human male genital tract are reported in this follow-up study of male offspring of DES-treated mothers. Both anatomical and functional abnormalities were significantly greater in the DES-exposed males as compared to control males whose mothers were all participants in a prospective, randomized double blind study of the effects of DES on pregnancy at the Chicago Lying-in Hospital during the early 1950s. Epididymal cysts, hypotrophic testes and capsular induration of the testes were among the more common genital lesions found in 27% of 134 DES-exposed males as compared to a 7% incidence in 119 control males. Spermatozoa analyses revealed severely pathologic changes (Eliasson score greater than 10) in 29% of 28 DES-exposed males and 0% of 18 control males (with or without genital i.e., physical abnormalities). Abnormal findings on physical examination combined with sperm abnormalities (Eliasson score greater than or equal to 5) were found in 29% of DES-exposed males versus 0% of 18 control males. Cytologic examinations did not reveal malignant cells from the following materials: urines before and after prostatic massage or ejaculation, prostatic fluids and aspirates from epididymal cysts.
