New Delhi VJ-turned-actor Ayushmann Khurrana, who is making his Bollywood debut with the film Vicky Donor, believes that stress and pressure of daily life has been harming the sperm quality in men over the last ten years. Vicky Donor, which is John Abrahams first film as a producer, is a romantic comedy based on the subject of sperm donation and infertility. Khurrana along with co-star, model-actress Yami Gautam walked the ramp in Mumbai recently for the promotion of the film. Well I think its a very noble cause, people should donate their sperm. There has been a considerable decrease in the sperm count of boys. In the last ten years, there has been a 15 percent decrease in the sperm count of boys, so I think its because of the stress and all the pressure of daily walks of life. The sperm donation has become really popular these days, nobody talks about it though, he said. The movie, directed by Shoojit Sircar, will hit theatres on April 20th.
