question: Hello doctor, I am 30 years old, and my wife too is 30 years old. We are trying for a baby for two to three months now with no success. I have erection problem if I try to do intercourse every day. In short, in between her 11th to 21st day of the period, I able to make intercourse for around four to five times. That is, I can get firm erection and ejaculation only once in two to three days interval. It is not working for us. Can you please tell any medicine to improve my erection? Will it harm the quality of sperm? Shall I use conceive plus fertility lubrication as my wife often face lubrication problem? Will it work for me? Do you like to suggest any sperm friendly lubricant? During her fertile period, how many times should we try to have intercourse?
