The role of the male partner in subfertility

We have all heard the saying ‘it takes two to tango’, but nowhere is it more relevant than in the accomplishment of conception. The first requirement for conception is that a sufficient number of fertile sperm are deposited in the correct place at the right time. It is therefore important that the man’s role in conception is assessed at the start of investigations for infertility, because it is inconvenient to find that the man is azoospermic after many months of unsuccessfully investigating and treating his female partner.
