Scientists have discovered plant extracts
According to foreign media reports, scientists have recently discovered a protein called ubenosideextractIt can reduce the motility of sperm, or it can be used as a raw material to make male oral contraceptives.
Ubunside can be extracted from the stems, roots, leaves, or seeds of the genus Pseudotiger thorn, as well as the croissants, and is used by East African tribes to cure the heart-stopping toxins on the arrowheads. According to recent research, Ubunside blocks the passage of sodium and calcium ions through a membrane protein called Na, k-atpases. Scientists say it is a key material for oral contraceptives for men.
However, this medication is harmful to the heart and cannot be taken alone.
