When it comes to infertility, roughly 30% of the issues may come from the man, 30% may be attributed to the woman, 30% may lie with both parties while the remaining 10% is typically the result of unknown causes.
It is quite common for me to see ladies who come for consultations without their partners as they think their struggles with pregnancy are due to underlying issues with them and not their husbands. However, I always advise couples to come for the initial consultation together to avoid unnecessary delays in diagnosis and for everyone to have a clearer picture of the situation.
