Male Factor

In the past, infertility was most often considered to be a woman’s problem, but this is far from true. In more than 30% of cases where a couple cannot conceive, the cause is attributed to male-factor infertility. Male-factor infertility is the inability to get an otherwise fertile woman pregnant. This is most often due to physical or hormonal problems, or lifestyle and environmental factors.

Male factor infertility is often related to:

  • Anatomic irregularities of the man’s reproductive organs
  • Childhood illnesses
  • Sperm production
  • Certain medications
  • Chronic health problems
  • Environmental factors or exposures
  • Previous injury or surgery


The best way to determine if a man is infertile is to do a comprehensive semen analysis. Tests may be performed to assess the total sperm count, the percentage of moving sperm (motility), the sperm shape (morphology), and/or the presence of a possible infection.


Treatments for male-factor infertility include medication, surgery to remove blockages, intrauterine insemination (IUI), and in-vitro fertilization (IVF). An additional option with IVF is to perform intra-cytoplasmic sperm injection (ICSI), which is a laboratory process of injecting sperm directly into a mature egg with a tiny needle during the IVF procedure.

At Colorado Reproductive Endocrinology, couples seeking infertility treatment for male infertility will find a program specifically tailored to their needs and designed to provide the very best chances of conceiving a child. Our doctors and medical team will present your options at every step of the way, provide support, listen to your questions and provide clear, understandable answers.


In order to avoid problems with future fertility, it is recommended that men avoid smoking, recreational drug use (especially marijuana), excessive alcohol use, performance-enhancing steroids, and excessive heat exposure to the testes from hot tubs or electronic devices, such as laptop computers.
