The rate of absorption into the embryonic chicken (Gallus domesticus) of 3H-testosterone.
The maximum absorption of tritiated testosterone by 5-day old embryos occurred one hour after its application to the eggshell. This decreased to relatively low levels during a 77 hour period. When the hormone was applied at the eleventh day of incubation there was a relatively large initial uptake by the bursa, spleen and thymus in that order and a subsequent diminution. Activity absorbed by the spleen remained essentially unchanged throughout the experimental period. The bursa appeared to have the greatest affinity for the hormone.
