Infertility （不孕不育）

Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most people and six months in certain circumstances. Infertility may be due to a single cause in either you or your partner, or a combination of factors that may prevent a pregnancy from occurring or continuing. Fortunately, there are many safe and effective therapies for overcoming infertility. These treatments significantly improve the chances of becoming pregnant.

• You're age 35 to 40 and have been trying to conceive for six months or longer
  

• You're over age 40
  

• You menstruate irregularly or not at all
  

• You have known fertility problems
  

• You've been diagnosed with endometriosis or pelvic inflammatory disease
