Document Summary
If you take a mom and stress her out, you administer stress to her and see that she will experience a peak in her testosterone levels by 2 days earlier than in non stressed animals. If you take the male fetuses, follow them as they go into adulthood, examine their sexual activity, you will see that they will have trouble ejaculating. Sdn-mpoa is usually larger in males than females but you see in these males it will not grow to the exact size that it should be in male rats. Maternal stress alters blood testosterone concentrations in fetal male rats, shifting the peak to 2 days earlier than that in nonstressed males. When tested as adults, sons of stressed mothers often failed to ejaculate in mating tests, even though their adulthood concentrations of testosterone and luteinizing hormone (lh) were normal. Prenatally stressed rats also display increased stress response compared to normal rats.
