You are right salih that stem 1 is TRUE as thereare UTERINE abnormalities which include classically hypoplastic T shaped uterus and occurs in 69%
STEM 2 is FALSE AS pregnency rate is not effected howwever ECTOPIC PREGNENCY rate is 10 fold

stem 3 is definately FALSE as there is no asssociation linked to it
stem 4 I m also doubt ful because I read that it does efffect quality of SEMEN but effect on sperm no is not known and according to RCOG statement it does reduce male fertility but how , it is not mentioned .Any body else can throw some light?

hi farah,

coming back to stem 4. I'll go with TRUE.

Undescended testicles or abnormally small testicles have been found in male fetus with in-utero DES exposure. No conclusive data about risk for testicular or prostate cancer is available. Data is also inconclusive about urogenital abnormalities in male off springs.

[ ref -- National Cancer Institute. DES Research Update 1999: Current Knowledge, Future Directions. National Cancer Institute, 1999. ]

Small testicles and undescended testis are associates with oligozoospermia, DES causes small and undescended testicles, and hence I go with true.

I spent a long time researching stem 4 and have to admit that I am still confused.

It is definitely associated with hypoplastic testes and cryporchidism but according to several reports and key texts, not oligospermia. In my experience the former testicle problems are almost always associated with some abnormality in the seminal fluid analysis so I expected it would also reduce male fertility but could not find this anywhere.

Male fertility
There appears to be some evidence from one study in the USA of a possible reduction of male
fertility
. The long-term UK study showed a correlation between single status and higher dose exposure earlier in pregnancy implying a possible interference with sexual function.

Just reading the guideline - and forgot what the consensus was on the course ... True???

yes - false; cryporchidism but not oligospermia.

Not sure I personally believe this but my opinion is unimportant.

The key here is that DES is associated with structural abnormalities of the reproducitve tract in both males and females.
