Answer me, Any possibilities to join navy if a person having medically unfit(left testis problem)

According to the Punjab and Haryana High Court, having a "one tes*****" does not constitute an impairment that would disqualify a candidate from serving in the Indian government army or navy

A bench made up of Justice G.S. Sandhawalia and Justice Vikas Suri made reference to a ruling by the Centre that the Respondent in this case is unfit for enlistment in the Navy since he only has one tes*****. So, going by this, you definitely have a shot at getting selected for the Indian Navy!

Hope I have answered your question. All the best!
