GONADAL HORMONES AND THE CONTRACTILITY Itf VITRO OF THE VAS DEFERENS OF THE DOG

Hormonal regulation of the micturition behavior of the dog.

“…No hematological studies were made on the puppies injected from the third day of life, but the anemizing effect of estradiol in the other 4 cases has previously been described (14). It was also found that castrated males treated with estradiol showed increased excitability of the vas del'crcns (15).…”

Hormonal regulation of rat seminal vesicle sensitivity to adrenaline, noradrenaline, acetylcholine and acetyl‐β‐methylcholine

“…He concluded that the seminal vesicles have both sympathetic and parasympathetic innervation. Later, the behaviour of genitals of male rats (Wilcke, 1937;Martins & Valle, 1939;Martins, Valle & Porto, 1939a;Valle & Picarelli, 1954), cats (Martins & Valle, 1940), rhesus monkeys (Martins, Valle & Porto, 1939b), rabbits (Porto, 1943), guinea-pigs (Valle & Porto, 1939), and dogs (Valle & Porto, 1947), and the responses of these organs to various drugs, were shown to be dependent on the hormonal state of the donor animals. In general, the seminal vesicle, the vas deferens, and the prostate of the castrated rat contracted spontaneously and rhythmically; organs from normal or testosterone-treated castrates were quiescent.…”
