False allegation on grounds of Impotency

Sir, I got married in July 2018. As my wife was not interested in sexual activities and avoiding me for reasons best known to her. Hence marriage was not consummated. Instead she complained to her parents that i have impotency hence cannot lead a happy marital life. After that she went to her parental home many times and stayed with her parents. Her parents didn’t show any interest to let her to live with me. She and her parents were allegedly calling me impotent guy in front of relatives and friends during a family function and did not let their daughter to live in my home. Even for Diwali they didn’t let her to our home for celebration and they were spreading stupid and false messages about me to my friend’s n relatives. In my 1 year of marriage life, she was with me only for 50 days and the remaining period she was with her parents and abusing me. She went and complained to state women commission that i am an impotent guy, hence she needs divorce. After thorough enquiry by the commission, her plea was rejected and they came to a conclusion that her version would be untrue. After that she withdrew her complaint and she issued advocate notice to me stating all blah blahs. Therefore, I sent her suitable reply notice to her. Within a week She had file a case under Section 12(1)(a) in The Hindu Marriage Act, 1955. 1. She is alleging that 40 sovereigns of gold were given to her by her parents at the time of marriage, but actually she never exhibited her jewels to us hence I don’t have any clue on that.So how do deal this allegation? 2. Next is Impotency, in order to protect from unnecessary comments passed by my wife and her parents I went for potency tests in a private hospital and now having a potency certificate.Is the certificate issued in private hospital is sufficient? Kindly advise me in this regard
