While your wife should see a gynaecologist, you should make a trip down to see the urologist.
I always tell my patients, for a man to be able to father a child naturally, there are 3 conditions that should be present:
- have a penile erection hard enough for penetrative intercourse
- be able to ejaculate inside the vagina
- have sperm in the ejaculated semen
If there are concerns regarding any of the above, you should see a urologist.
