it is an alarming sign of infertility. these factors mentioned are true and important. professional, pesticides, laptops, are the main sources  but in my opinion the uses of internates, films, TV, porn sites  use are more in children and young s. i have seen so many my patients  are facing the problem of erectile dysfunction, impotency and mostly are engulfed by masturbation and premarital sex.on the other sides the girls are inclined to much abortions more uses of contraceptives and some are interested IVF.
 IF THIS TREND WILL CONTINUE SO SEXUAL CRIMES INCREASED and mental illness like depression and suicidal cases will increased and family life will disturbed and divorces will increase.and in future there will be no need of family planning.
