Male Infertility and Sexual Dysfunction

Conditions we treat within this category include:

  • Erectile dysfunction
  • Ejaculatory disorders
  • Fertility preservation in men with cancer
  • Hypogonadism (low testosterone)
  • Klinefelter’s syndrome
  • Peyronie’s disease
  • Testicular failure
  • Varicocele

Infertility affects approximately fifteen percent of couples trying to initiate a pregnancy and male factors are responsible in up to 50% of couples struggling with infertility. Our program conducts state-of-the-art testing and research to assist in the evaluation of male factor infertility in addition to fertility preservation for males with cancer.

Sexual dysfunction includes erectile dysfunction, decreased libido, change in penile shape, ejaculation problems and orgasm alterations. The goal of our research and patient care is to restore sexual function and intimacy for men with sexual dysfunction.


Research initiatives are focused on the evaluation of treatments to manage both the physical and psychosocial causes of sexual dysfunction. Our male infertility researchers specialize in oncofertility, which combines the fields of oncology and reproductive medicine to expand fertility options for cancer survivors.

 Patient Care

Our faculty provide comprehensive, state-of-the-art medical care to men experiencing fertility problems. We work closely with our reproductive endocrinology colleagues (female fertility specialists) in the use of assisted reproductive techniques such as intrauterine insemination (IUI) and in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). This collaborative approach maximizes the male and female partners' fertility status and helps to expedite care.

The Sexual Dysfunction Program provides a complete evaluation for men with erectile dysfunction and ejaculatory disturbances. This includes the evaluation of factors that can influence dysfunction, including hormonal, vascular, neurologic and psychological factors.
