The sperm is deposited at the cervix but what goes up must come down. Standing on your head is an old wives tale lol... Some women do lift up their pelvis by using a pillow underneath after sex for about 20 minutes. Whether or not it helps, is a matter of how things go and how healthy your sperm is and how healthy your wife is. It can take even a healthy couple 6 months to a year or more to conceive. Eat a balanced diet, exercise and time ovulation to the best of your ability. Usually a woman will ovulate 12-14 days before her period, if she has a regular cycle. If not, then try using opk's (ovulation predictor kits) to pin point when she will ovulate. Just lie down after sex and wait about 10-20 minutes. Good luck and hoping for the best.
i know it sounds strange but tell her after sex to stand on her head for 3 minutes hopefully she will conceive
