What was studied?
A tilapia experiment measured feeding, testicular development, androgen-receptor expression and circulating hormones after repeated exposure.
What did the researchers report?
The study reported changes in germ-cell stages and several reproductive markers, without a corresponding difference in one measured hypothalamic-pituitary staining endpoint.
What are the limits?
Fish endocrine biology and experimental exposure differ from human physiology. These findings cannot justify human fertility, hormone or performance claims.
