My husband and I are trying to conceive a girl. We have been trying for quit some time now to have kids. We have not been very successful. We want to know what we have to do in order to conceive a girl. What are the biological terms that help in making a girl child? If we do not succeed on our own what are the other terms we can consider. What is a test tube baby, and how does it work. Please we really are desperate to have a girl child, help us!
