Each of these reviews used different inclusion and exclusion criteria for trials. Our aim in producing this review is to bring together all randomised studies in t...

In the bird, the testis is much more responsive to any type of stimulation than is the ovary, while in the mammal the reverse seems to be true. It was also shown relatively early that the chorionic gonadotrophins secreted in the urine ...
Adult C57B1/Icrc female mice were given a single total body dose of 300r X-rays. They were mated with non-irradiated litter-mates and the progeny maintained over several generations. Some of the females of the 17th generation of this population gave birth to litters with phenotypic characters different from the original parents. At maturity the total gonadotrophins of the pituitaries of these a...
