DES exposure in utero associated with cryptorchidism, testicular hypoplasia and semen abnormalities

Severe pathological changes found in many DES Sons’ sperm.

Abstract

Association of diethylstilbestrol exposure in utero with cryptorchidism, testicular hypoplasia and semen abnormalities, The Journal of urology, NCBI PubMed PMID: 37351, 1979 Jul.

Epididymal cysts and/or hypoplastic testes have been found in 31.5 per cent of 308 men exposed to diethylstilbestrol in utero, compared to 7.8 per cent of 307 placebo-exposed controls.

Analyses of the spermatozoa have revealed severe pathological changes (Eliasson score greater than 10) in 134 diethylstilbestrol-exposed men (18 per cent) and 87 placebo-exposed men (8 per cent).

Further investigation of the 26 diethylstilbestrol-exposed men with testicular hypoplasia has revealed that 65 per cent had a history of cryptorchidism.

Only 1 of the 6 placebo-exposed controls with testicular hypoplasia had a history of testicular maldescent.

Although none of our Diekmann’s lying-in study group has had carcinoma to date one must keep in mind the reported increased risk of testicular carcinoma in testes that are or were cryptorchid.

A 25-year-old man who was not part of the study group was treated recently by us for a testicular carcinoma ( mixed anaplastic seminoma plus embryonal cell carcinoma) and he had a history of diethylstilbestrol exposure in utero and cryptorchidism.
