Contraceptive Drugs Market: New Male Contraceptive Reduces Sperm Count by 45% in Mice

The growth of the global contraceptive drugs market is driven by alarming increase in the incidence of STDs, rise in unintended pregnancy rate, and need for family planning across the world, owing to rapidly growing population and socioeconomic burden related to teenage pregnancy. The impact of the drivers is expected to surpass that of the restraints. 

the global contraceptive drugs market size was valued at $14.32 billion in 2019, and is projected to garner $24.41 billion by 2027, registering a CAGR of 6.9% during the analysis period.

 


Growth in need to prevent unwanted pregnancy, surge in awareness for contraceptives across the world, and rise in usage of oral contraceptives as a preferred method to avoid unplanned pregnancy drive the growth of the global contraceptive drugs market. In addition, increase in government and NGO initiatives promoting contraceptives and mounting awareness about STDs further fuel the growth of the global market. However, health risks related to the use of contraceptive methods restrain the growth to some extent. Nevertheless, rise in disposable income, growth in demand for healthy life in emerging economies, and presence of large unmet contraceptive needs in emerging Asian and African economies are anticipated to present an array of opportunities in the near future.

Limited contraceptive options

People who produce sperm are currently limited to two forms of contraception – condoms, which can fail, and a vasectomy, a surgical procedure that is regarded as a permanent form of sterilization. A 2019 survey by the Male Contraceptive Initiative found that 70% of men in the United States aged 18–44 are “somewhat or very interested in new male contraception.”

EF-4-177 reduces sperm count by 45% in mice

The researchers sought to develop a drug that inhibits a protein called cyclin-dependent kinase 2 (CDK2), which belongs to the cyclin-dependent kinase protein family. This family of proteins is involved in sperm cell production and tumor development. Mice lacking the CDK2 receptor are sterile, suggesting it could be an effective target for inhibition as a contraceptive. However, the receptor is structurally similar to other enzymes within the CDK family, therefore increasing the likelihood of off-target effects.

They selected one molecule for further optimization: EF-4-177, which bound to CDK2 more strongly than the dye. Georg and team found that this compound demonstrated a long half-life in mice, and after 28 days’ exposure, the animals’ sperm count reduced by 45%. “This work details the discovery of the highest affinity allosteric CDK inhibitors reported and shows promise for this series to yield an efficacious and selective allosteric CDK2 inhibitor,” the researchers write.
