Soya makes it hard to get pregnant

Hmm... so couples trying to get pregnant shouldn't drink tau huey zhui and other such soy products? Ah. Suddenly there's a whole new way of looking at the birth rates in Singapore...



This is true! One of my lectures at med school was on phytoestrogens like those found in soya, and the effect on fertility/sexual vigor in animals (rats and fish, mostly).

There haven't been any studies conducted on humans, as far as I can tell. The only way is to study vegan or vegetarian populations who depend on soya as a protein source - Hindus or Japanese vegetarians, for example? They seem pretty fertile to me, though.


Huh? Cannot be lah...... :)

Doctors are very interested in the properties of phytoestrogens for the treatment of menopause and hormone-linked cancers like prostate cancer.
