A Case Study: Unraveling Male Infertility Caused by Low Semen Volume
Male infertility is an often-overlooked piece of the puzzle when couples struggle to conceive. While women typically undergo numerous evaluations, men are sometimes reluctant to pursue testing. In my years as a fertility specialist, I’ve encountered countless cases where the root cause of infertility was linked to male factors, particularly low semen volume. One such case stands out, not only because of its complexity but also because of the profound impact it had on the couple involved—and on me as their doctor.
The Case: A Complicated Journey
David, 37, and his wife Sarah, 34, had been trying to conceive for three years. Sarah had undergone a full fertility workup at her gynecologist’s office and was told everything appeared normal. Despite this, they were unable to conceive. Frustrated but hopeful, they sought a second opinion and came to my clinic.
David initially seemed hesitant during our first meeting. “I don’t think I’m the problem,” he said, half-jokingly. “I’ve never had any issues before.” Sarah nodded in agreement, but she also expressed her growing frustration and anxiety about their situation.
This is a common dynamic I see—men often assume their role in infertility is minimal. But as I explained to David and Sarah, male factors contribute to approximately half of all infertility cases. A thorough semen analysis is a vital step in the diagnostic process.
The Diagnosis: Pinpointing Low Semen Volume
David’s semen analysis revealed a significant issue: his semen volume was only 0.6 milliliters, far below the normal range of 1.5 to 5 milliliters.
While his sperm concentration and motility were within acceptable limits, the low semen volume was a major barrier. Without enough seminal fluid to transport sperm effectively, the chances of natural conception were drastically reduced.
I explained this to David in simple terms: “Think of semen as the vehicle for sperm. Without enough fluid, it’s like trying to drive a car without fuel—it’s hard to get where you need to go.”
Investigating the Cause
Low semen volume can result from a variety of conditions, so our next step was to identify the underlying cause. Here’s how we approached David’s case:
- Hormonal Evaluation
Blood tests revealed that David’s testosterone levels were borderline low, while his follicle-stimulating hormone (FSH) was slightly elevated. This suggested his testicles were working harder than they should to produce sperm, potentially indicating a subtle hormonal imbalance. - Imaging and Physical Examination
A scrotal ultrasound ruled out a varicocele (enlarged veins in the scrotum), a common cause of male infertility. However, a transrectal ultrasound revealed partial obstruction in his ejaculatory ducts, which was preventing his seminal vesicles from fully releasing fluid. - Lifestyle Assessment
David admitted to spending long hours in a hot tub after work—a habit he used to relax. Prolonged exposure to heat can impair sperm production and reduce seminal fluid output. He also noted frequent dehydration due to his busy work schedule.
The Treatment Plan: A Comprehensive Approach
Addressing low semen volume often requires a multi-faceted approach. For David, we developed a customized plan that included:
1. Surgical Intervention
To resolve the partial obstruction in his ejaculatory ducts, David underwent a minimally invasive procedure called transurethral resection of the ejaculatory ducts (TURED). This helped restore normal seminal fluid flow.
Dr. Anthony Warren, a urologist who collaborated on this case, explained:
“Even a small obstruction can significantly impact semen volume. Surgical correction is often straightforward and highly effective.”
2. Hormonal Therapy
To address David’s low testosterone levels, we initiated a carefully monitored regimen of clomiphene citrate, a medication that stimulates the body’s natural testosterone production without suppressing sperm production.
3. Lifestyle Modifications
David made several changes to his routine:
- He reduced his use of hot tubs and avoided prolonged heat exposure.
- He increased his daily water intake to maintain proper hydration.
- He began managing work-related stress through mindfulness techniques and physical activity.
Monitoring Progress
Three months after beginning treatment, David’s semen volume had increased to 2.2 milliliters—well within the normal range. While this was an encouraging milestone, the couple still hadn’t conceived after another six months of trying.
At this stage, we decided to introduce intrauterine insemination (IUI) to maximize their chances. During IUI, we processed David’s semen sample to concentrate the healthiest sperm and placed it directly into Sarah’s uterus during her fertile window.
The Outcome: A Successful Pregnancy
On their third cycle of IUI, Sarah became pregnant. The joy and relief on their faces during our follow-up appointment were unforgettable. “It feels like we’ve been given a second chance,” David said.
Reflections on the Case
David’s case highlights several important aspects of treating male infertility caused by low semen volume:
- Male Infertility Requires Equal Attention
Infertility is a shared challenge. Comprehensive testing for both partners is essential to uncover the full picture. - Low Semen Volume Can Be Treated
Many men with low semen volume assume their condition is untreatable, but advancements in medicine have made solutions highly accessible. - Collaboration Is Key
Working with a multidisciplinary team—including urologists, endocrinologists, and fertility specialists—ensures that patients receive the most effective care. - Patience and Persistence Pay Off
Fertility treatment often requires multiple attempts and a willingness to adapt the plan. Success rarely comes overnight, but persistence leads to results.
Advice for Men Facing Low Semen Volume
If you or your partner have been diagnosed with low semen volume, here are my recommendations:
- Seek Expert Help: A fertility specialist or urologist can help pinpoint the cause and develop a tailored treatment plan.
- Don’t Underestimate Lifestyle Factors: Small changes, like staying hydrated and avoiding heat exposure, can make a significant difference.
- Be Open to Advanced Treatments: Techniques like IUI or IVF can help overcome obstacles when natural conception isn’t possible.
Conclusion: Hope for the Future
David and Sarah’s journey reminds us that infertility is not a roadblock but a detour—one that requires patience, determination, and expert guidance. Low semen volume, while challenging, is highly treatable with the right approach.
As a fertility specialist, I’ve seen many couples face similar struggles, and I’ve also seen how those struggles can lead to triumph. If you’re navigating a similar path, know that there’s hope—and with the right care, your dream of building a family can become a reality.
