A post coital test has also been used at some clinics in the past and may still be required.
It often seems that these tests can be endless and you may ask yourself why do they need to be repeated again and again.
The results of these tests can prove highly emotional as you may feel you have failed in you manhood or womanhood. If your partner has the problem then they may feel a a failure and question your commitment to them. If you have the problem then you may feel that your partner doesn't understand the emotional pressure that you feel under being unable to provide them with a child.
The simple answer to all of these issues is that there is no simple answer unfortunately. The only advice that should really be offered is COMMUNICATE with your partner. Share your fears and feelings with them. LISTEN to their needs and concerns.
The journey is a long and hard one and at the end it is likely that your relationship will be stronger or possibly in tatters!!!
