Male Infertility

Male infertility is a factor in more than half of infertile couples’ inability to conceive. If you and your partner have been trying to conceive for more than a year without success, you should seek a fertility evaluation. Additionally, if you have had a vasectomy and wish to have more children, we also offer vasectomy reversals.

  • To provide you and your partner with the best chance of success, our team works with experts across endocrinology and reproductive endocrinology to create a personalized treatment plan, always keeping your priorities and family goals at the forefront. 
  • We’ll ensure that underlying health concerns are addressed, both to maximize your fertility and to improve your overall well-being. 

Male Infertility Experts 

You’ll be under the skilled and compassionate care of the Director of Male Infertility and Men’s Health, Amin Herati, M.D., whose multidisciplinary approach incorporates experts from other Johns Hopkins divisions, when needed. 


What to Expect 

Because male infertility has so many possible causes, we approach diagnosis and treatment systematically, while taking into account the couple's age, family goals and priorities. 

Your fertility evaluation will begin with a review of your medical history and a physical examination, followed by some initial laboratory tests. These tests include one to two semen analyses plus bloodwork to evaluate your hormone levels. Depending upon these results, a more detailed evaluation may include: 

  • Repeat semen analyses 
  • More specific sperm function tests 
  • Additional hormonal or genetic tests 
  • Novel imaging tests 
  • Testicular biopsy  

Based on the findings, we’ll recommend an individualized assessment and treatment approach. Usually this process is a collaboration between your male infertility specialist, reproductive endocrinologists and gynecologists.
