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.

  • Conventional IVF – large dosages of fertility medication are administered to produce 10+ egg follicles for fertilization in vitro
  • Mini-IVF™ – minimal dosages of fertility medications are administered to produce between 3 and 5 eggs for fertilization in vitro
  • Natural Cycle IVF – no fertility medications are administered and one good natural egg is harvested for fertilization in vitro

Causes of Secondary Infertility

The causes of secondary infertility are very close to the causes of primary infertility. The human reproductive system changes over time and medical conditions arise.

Causes of secondary infertility include:

  • Low sperm production
  • Poor sperm motility – delivery
  • Poor sperm quality – morphology
  • Irregular or no ovulation in women
  • Hormonal issues for both men and women
  • Damaged reproductive organs for women, including damage that may have occurred during a previous pregnancy

If you’re struggling with conceiving after already having had a child, speak with your doctor about secondary infertility treatment. To begin, both partners will undergo testing to identify the root cause of the secondary infertility. Then, a personalized treatment plan will be developed addressing your medical needs while incorporating your desires.

Coping with Secondary Infertility

Just as with primary infertility, there is an emotional toll that comes with being unable to conceive. Those who have children may feel guilty about yearning for another child when they already have a child. Others may find it harder to find support from others who do not understand the desire to continue to grow your family. Coping with these emotions is an important part of your treatment and is necessary to make it through the fertility process. New Hope Fertility NYC offers support groups to help patients address these feelings and concerns.
