What Are the Main Causes of Infertility in Women and Men?
Infertility affects around 1 in 7 couples in the UK. If you are struggling to conceive, you are not alone. At Marylebone Diagnostic Centre, 73 Baker Street, London W1U 6RD, we offer advanced fertility screening tests for both men and women. Our aim is to identify causes early and help you move forward with confidence.
What Does Infertility Mean?
Infertility is when a couple cannot conceive naturally after 12 months of regular, unprotected sex (or 6 months if the woman is over 35).
It can affect either partner, which is why a fertility MOT London is essential for both men and women.
