Infertility

摘要

There are many reasons why a couple may not be able to conceive.Female infertility can,for example,be elicited by blocked oviducts,hormonal disorders,ovulation difficulties or disturbed nidation.The chief factor in male infertility is the quality of sperm;too few,insufficiently mobile and non-viable sperm can render the conception to a major problem.Fortunately,assisted reproduction offers a successful treatment option for many of these couples.
