New Non-Hormonal Male Contraceptive Shows Promise in Reducing Sperm Production

Houston, Texas, Texas, USA United States of America
CDD-2807 targets the protein STK33, which plays a crucial role in sperm functionality.
In mice studies, CDD-2807 effectively suppressed sperm production without significant side effects or affecting other reproductive functions.
Researchers at Baylor College of Medicine have developed a non-hormonal male contraceptive called CDD-2807.
The gel form of CDD-2807 applied daily to the shoulders reached low sperm levels in 80% of men within 12 weeks.
These findings mark an important step forward for male contraception research.
New Non-Hormonal Male Contraceptive Shows Promise in Reducing Sperm Production

Researchers at Baylor College of Medicine have made significant strides in the development of a non-hormonal male contraceptive. Two promising studies, published in Science and NIH's Contraceptive Development Program, reveal that CDD-2807, a compound targeting the protein STK33 enriched in mammalian testes, effectively reduces sperm mobility and numbers without significant side effects. The contraceptive effect is reversible.

The first study published in Science reported that CDD-2807 inhibits the protein STK33, which plays a crucial role in sperm functionality. In mice studies, the compound effectively suppressed sperm production without causing significant side effects or affecting other reproductive functions. The researchers noted that this non-hormonal approach could provide an alternative to hormonal methods for male contraception.

The second study published by NIH's Contraceptive Development Program revealed that the gel form of CDD-2807, applied daily to the shoulders, reached low sperm levels in 80% of men within just 12 weeks. The hormones are absorbed by the bloodstream when rubbed into the skin and have shown promise in clinical trials.

These findings mark an important step forward for male contraception research. With continued studies and development, these non-hormonal methods could offer a more convenient, effective, and side-effect free alternative to hormonal birth control options for men.
