What causes Infertility

What causes Infertility?: 1 of 5 things you really need to know about infertility


 A Couple’s Guide to Infertility

(Dr Eric Daiter, Board Certified in Reproductive Endocrinology and Infertility)


The goal of this guide is to provide a medical expert’s answers to the common questions:

What causes infertility?

Identifiable causes of infertility can be grouped into female egg issues (including problems with ovulation, irregular menstrual cycles intervals, hormonal imbalances), male infertility (including low sperm count, abnormal sperm motility or shape, decreased sperm function), and female pelvic problems (including blocked or damaged fallopian tubes, endometrial polyps, scar tissue, endometriosis).  Unexplained infertility is when the cause of infertility is not yet identified.  The cause for infertility remains unexplained in only about 5-10% of couples after a thorough evaluation has been completed, so completion of all available diagnostic tests is often very helpful.

Most medical research concludes that roughly one third of infertility problems are entirely a female problem, one third are entirely a male problem and one third are a combination of male and female problems.  Therefore, assumptions regarding the likely causes (for example, I’m sure it is “his fault” or it’s probably “her fault”) are often misleading and a thorough evaluation really needs to be completed to identify the actual problems.

Common female causes of infertility include (1) ovulation disorders that may result from

  • stress, including emotional stress or physical stress due to excessive exercise, starvation or binge dieting,
  • hormonal imbalances involving the thyroid gland, excessive prolactin secretion or excessive androgenic hormones,
  • dietary intake of large amounts of estrogen containing foods,
  • certain medications,
  • prior ovarian or pelvic surgery,
  • injury to the ovary

and (2) pelvic disorders that may result from

  • scar tissue or damage to the fallopian tubes or uterine cavity as a result of inflammation due to infection, endometriosis, ruptured ovarian cysts, pelvic surgery, or the presence of foreign materials;
  • fibroids,
  • persistent nonfunctional ovarian cysts,
  • endometrial polyps

Common male causes of infertility include (1) abnormal sperm production or function possibly resulting from

  • undescended testes at birth,
  • bladder surgery as a newborn,
  • a varicocele,
  • genetic abnormalities,
  • poor dietary habits,
  • excessive use of tobacco or alcohol or drugs,
  • exposure to environmental toxins such as heat or some chemicals,
  • certain medications

and (2) problems with the delivery of sperm at intercourse possibly related to

  • erectile dysfunction,
  • premature ejaculation,
  • blockage within the vas deferens or urethra- tubes that allow transport of testicular sperm from within the scrotal sac through the pelvis and penis
