I assume that you are refering to taking these anti-estrogen drugs while on cycle?

The evidence seems to suggest otherwise.

Here is a couple of extracts from building the perfect beast

"DHT (dihydrotestosterone)
DHT elevation from AAS use has been blamed for everything from balding to
prostate cancer. Just to throw a wrench in the media and AMA dogma machine...
consider this: A so-called "normal" blood testosterone level/reference range for a
male is 300-1000ng/dl, and 14-76ng/dl for "normal" females. DHT is a metabolite of
testosterone due to reduction by the 5a-reductase enzyme.
Now, look at the above male and female reference ranges and answer a few
questions:
1. Why are 40% of the world's females facing noticeable thinning hair by age 40?
2. Why has DHT been approved and patented as a treatment for BPT and prostate
enlargement?
3. If male testosterone levels decrease as they age, and DHT is a product of
testosterone, then why does the chance of experiencing BPT, prostate cancer, and
balding increase with age? (Females do not have prostate glands)
There is a great deal of evidence to support the belief that estrogenic activity in
the presence of DHT and an environment of low testosterone production may be the
main cause of BPT and attributory toward prostate cancer. However, too much of
anything can eventually be the cause or mediator of a negative reaction."

Another One.

"Testosterone reduces to DHT (dihydrotestosterone) so testosterone will increase the
risk of prostate cancer, right? It should be of interest to hear that DHT has been patented
as a treatment for BPH (Benign Prostate Hyperplasia). However several studies have shown
that estrogen elevation and subsequent interaction with factors of DHT activity cause the
negative effects in prostate size and PSA levels. (Prostate-Specific-antigen) (Is estrogen evil?)
"Kenny, A.M., et al. (2000) Endocr. Res. 26 (z): 1 53-68 "Cooper, C.S., et al. (1 998) J. Urol 1
59 (2): 441 -3"

So it seems to suggest that it is an interaction with elevated estrogen and DHT that can cause problems. Therefore it should follow that controlling estrogen when you have elevated DHT levels (while on a test cycle for example) is a very good idea.
