Key result
Gonadectomy reduces Coxsackie B1 mortality in mice, but protection wanes after 30 days.
Why the study?
The study investigated the effect of gonadectomy on susceptibility to Coxsackie B1 virus infection in adult mice due to observed high virulence and mortality.
Answers are grounded in this paper and cite their sources.
Gonadectomy may transiently lower Coxsackie B1 mortality in mice; hypothesis-generating for hormonal effects on viral susceptibility in humans.
The Coxsackie B1 virus used in this experiment was unusually virulent for adult “Swiss albino” mice; approximately 15% of the infected animals died and the survivors were severely ill. However, following gonadectomy the death rate fell significantly. This protective effect of castration was not sex-linked and was no longer present 30 days after surgery. Possible hormonal mechanisms responsible for this altered susceptibility are discussed.

Sumner Berkovich (1965) studied Coxsackie B1 Virus Infection. Gonadectomy vs. Intact (non-gonadectomized) mice was evaluated on Death rate. Gonadectomy significantly reduced the death rate of adult Swiss albino mice infected with Coxsackie B1 virus, though this protective effect was no longer present 30 days after surgery.
