Is it Time for You to See a Fertility Doctor?


shutterstock_192934715If you are under 35 and have not been able to get pregnant after having regular, unprotected sexual intercourse for at one year, you should see a fertility doctor. For women over 35, the time period for trying to get pregnant naturally is shortened to six months. Look: A woman’s fertility is dependent upon her overall health, wellness and lifestyle choices. Many women suffering from infertility use up too much valuable time trying to conceive naturally when there is a simple medical solution to their problem. Bottom Line: Don’t delay treatment.

When to See a Fertility Doctor

Infertility can be difficult to diagnose. The sooner you seek help from a fertility doctor, the less time you will waste trying to get pregnant.

  • A woman’s peak fertility years are in her 20s to mid-30s
  • Women in their peak fertility years have a 20 percent chance of pregnancy every month
  • A woman’s fertility level begins to decline after 30 and there is a precipitous drop after she turns 35
  • Women over 40 only have about a 5 percent chance of getting pregnant during any given month

Fertility Doctor Treating Secondary Infertility

While it is mainstream for a couple to seek out the help of a fertility doctor after they have tried unsuccessfully to get pregnant for a year, a typical case of secondary infertility can go undiagnosed. Primary infertility is diagnosed when a couple fails to conceive after one year of regular, unprotected sex. For women over 35, this time period is shortened to six months. Secondary infertility is diagnosed when a couple has been successful in conceiving a child, but then is unable to conceive more children.


Dr. John Zhang is renowned for successfully treating couples suffering from secondary infertility. Older men and women considered poor responders are turned down by other fertility clinics offering In Vitro Fertilization (IVF).

Dr. John Zhang welcomes patients representing a challenge, regardless of their potential adverse affect on his pregnancy success rates. The Doctor completed his clinical training at NYU and holds a PhD in IVF from Cambridge. With over two decades of experience in Reproductive Endocrinology, the Doctor is a leading authority performing a vast array of IVF methods.
