HI, thanks for using healthcare magic It is unlikely that this injury would have significantly affected your ability to conceive. There are different reasons for infertility. It can be due to male or female causes or due to a combination. In terms of your partner, you are right in assuming that he would need a semen analysis. The cost would vary according from one lab to the next. He can either consider speaking to his urologist , speaking to a lab directly to find out the cost. In terms of your investigations, your doctor would need to assess the different aspect of the reproductive system- the uterus, ovaries, tubes, cervix This would involve both imaging and blood tests. You should consider visiting your gynaecologist or a fertility specialist. Even if issues are found with either of you there are effective techniques available that may be able to help you conceive. I hope this helps
