In a examine with mice, researchers funded by the US National Institutes of Health have recognized a possible non-hormonal contraceptive that males may take shortly earlier than sexual exercise and regain fertility the subsequent day, they report within the journal Nature. Communications’.
The researchers gave male mice a compound that briefly deactivates soluble adenylyl cyclase, the enzyme important for activating a sperm’s means to swim and mature in order that it will probably journey by way of the feminine reproductive tract and fertilize an egg.
In a number of checks, the researchers demonstrated that the compound TDI-11861 immobilized mouse sperm and prevented their maturation. The compounds didn’t intrude with the sexual functioning of the animals.
Although the male mice did mate with the females, no pregnancies have been noticed. Sperm recovered from feminine mice remained incapacitated. In addition, they noticed no uncomfortable side effects in both male or feminine mice, and the impact of the compound disappeared three hours later, when the males regained their fertility.
The researchers say their work demonstrates that soluble adenylyl cyclase inhibitors might present a protected, on-demand, non-hormonal, reversible oral contraceptive for males.
