US analysts say the poke was right around 96 percent successful in tests on around 270 men who were utilizing it, with four pregnancies among their accomplices.
In any case, a moderately high number created symptoms, including skin inflammation and state of mind issue.
Analysts have been exploring potential for male hormonal contraceptives for around 20 years.
They have all been searching for a compelling method for stifling sperm generation without causing obnoxious or insufferable reactions.
Since men always create sperm, abnormal amounts of hormones are expected to decrease levels from the ordinary sperm check of more than 15 million for every milliliter to under one million/ml.
This investigation was distributed in the Journal of Clinical Endocrinology and Metabolism, and distributed by the Endocrine Society.
It took a gander at men matured 18-45 who had been in monogamous connections for no less than a year - and whose accomplices had consented to participate.
They at that point had two hormone infusions (progesterone and a type of testosterone) at regular intervals, and were observed for up to a half year until the point that their sperm tally tumbled to under a million.
Dr Mario Festin, of the World Health Organization (WHO) in Geneva, who completed the investigation said "The examination discovered it is conceivable to have a hormonal preventative for men that decreases the danger of spontaneous pregnancies in the accomplices of men who utilize it."
The analysts quit going up against new members in 2011 after concerns were raised about reactions, for example, dejection and other mind-set issue, and also muscle agony and skin break out.
Dr Festin said different specialists were presently taking a gander at consolidating distinctive levels of similar hormones, and diverse methods for conveying them, for example, gels.
Allan Pacey, teacher of andrology at the University of Sheffield, said "There is surely a neglected requirement for a powerful reversible preventative for men, along the lines of the hormonal prophylactic for ladies."
"Be that as it may, none of the arrangements that have been created and tried to date have figured out how to wind up noticeably a business reality for some reason."
He said the prophylactic in this examination was "to a great degree compelling and subsequently unquestionably has guarantee" and that the quantity of symptoms seen was a worry.
Be that as it may, he included "It is important that 75 percent of the men who participated in the trial would utilize this strategy for contraception once more."
