Long-term male contraception method is both reversible and noninvasive may soon be available thanks to the work of Chinese experts.
In a paper published recently in the journal ACS Nano, Chinese scientists from Harbin Medical University and the National Center for Nanoscience and Technology revealed a hydrogel injected into a man’s spermaduct that can remove with extracorporeal ultrasound.
Women’s health suffers as a result of over half of all pregnancies being unplanned. It mostly owing to the failure of contraception. Condoms and vasectomy, the most common method of male contraception, cannot be both highly effective and reversible.
Anhydrous titanium dioxide, calcium chloride, and sodium alginate have combined with thioketal to form the hydrogel, according to the findings of the study.
After injected into the vas deferens for a single time, the combination agents may go from liquid to hydrogel. It effectively plugging the tubes and impeding sperm movement, according to the study.
Fertility can restore by using noninvasive remedial ultrasonography to create reactive oxygen species. It which subsequently cleaves the thioketal hydrogel network.
According to the findings of the study, the fertility rate has restored to 100 percent. Occlusion and recanalization can also monitored in real time using ultrasounds, of course.
The researchers believe that this method might one day utilise as a safe, effective, and reversible male contraceptive method to meet the growing need among men to better manage their reproductive health.
