Breaking Down Male Factor Infertility
June is Men's Health Awareness Month, a time dedicated to encouraging men to take a more active role in their physical and mental well-being. At Aspire Fertility, we think that conversation needs to include something that often gets left out: male fertility.
About 1 in 6 couples in the United States experience infertility. Of those, male factor issues are a contributing cause in approximately 40–50% of cases, and the sole cause in about 30%. Yet men are far less likely to seek evaluation, and even less likely to talk about it.
Causes of Male Factor Infertility
There are many potential causes of male factor infertility, but there are four main kinds.
Structural Abnormalities are obstructions that partially or totally block the flow of sperm or semen. In some cases, these abnormalities are present at birth. In others, they occur after infection of the urogenital tract, or after surgery.
Sperm Production Disorders result in sperm production becoming inhibited. Possible causes include:
- Vasectomy, a surgical procedure for male sterilization. During the procedure, the ducts that transport sperm are severed and then sealed to keep sperm from entering into the semen, which prevents fertilization.
- Varicocele, an enlargement of the veins within the scrotum. Varicoceles develop over time and are similar to varicose veins in the leg. Although many varicoceles have no effect on sperm production or quality, they are a common cause of sperm production disorders.
Ejaculatory Disturbances prevent sperm from reaching the egg. There are several types:
- Retrograde Ejaculation occurs when semen enters the bladder instead of emerging through the penis during orgasm. Although men can still reach sexual climax, they may ejaculate little or no semen (sometimes called a "dry orgasm").
- Erectile Dysfunction occurs when a man has consistent and repeated problems sustaining an erection. Without treatment, erectile dysfunction can make sexual intercourse difficult.
Immunologic Disorders. Endocrine disorders or antisperm antibodies prevent sperm from meeting and successfully penetrating the egg in the female reproductive tract.
What a Semen Analysis Tells You
A semen analysis is one of the simplest, most informative tests in reproductive medicine. It evaluates:
- Sperm count: how many sperm are present
- Motility: how well they move
- Morphology: their shape and structure
- Volume and pH: the overall health of the sample
It's non-invasive, takes less than an hour, and can give you a clear picture of where things stand. If there's an issue, knowing sooner means more options: lifestyle changes, medical treatment, and fertility preservation.
Lifestyle Factors That Affect Sperm Health
Men's Health Month is a great time to take stock of daily habits. Several common lifestyle factors have a documented impact on sperm quality:
Heat exposure. The testes are located outside the body for a reason: sperm production requires a temperature slightly below core body temperature. Frequent hot tub use, saunas, or even keeping a laptop directly on your lap for extended periods can have a measurable effect.
Smoking and alcohol. Both have been linked to reduced sperm count and motility. Cutting back or quitting can lead to meaningful improvement within a few months.
Stress. Chronic stress raises cortisol levels, which can suppress testosterone and interfere with sperm production. This is one area where mental health and reproductive health are directly connected.
Nutrition and weight. Obesity is associated with hormonal changes that can impair sperm production. A balanced diet rich in antioxidants, including leafy greens, berries, nuts, and lean protein, supports sperm health at the cellular level.
Anabolic steroids and testosterone therapy. Men sometimes don't realize that exogenous testosterone, whether prescribed or used recreationally, can significantly suppress the body's natural sperm production, sometimes to zero. If you're currently on testosterone therapy and thinking about starting or expanding your family, this is a critical conversation to have with a fertility specialist before it becomes a problem.
When to See a Specialist
If you and your partner have been trying to conceive for 12 months without success (or 6 months if your partner is over 35), it's time to seek an evaluation, for both of you. That includes a semen analysis.
This June, we're inviting men to take one step: make the call. Get the evaluation. Talk to your partner. Talk to your doctor. At Aspire Fertility, our team evaluates male factor infertility with the same depth and compassion we bring to every patient.
