Evaluation and Management of Male Factor Infertility

Semen Analysis Interpretation

The American Academy of Family Physicians and The Journal of Urology recommend that a sperm count of 3 million/mL is significantly below the normal reference range, indicating severe oligozoospermia, with motility of 50% being borderline normal 1, 2
The combination of severe oligospermia and asthenozoospermia significantly reduces natural fertility potential, indicating male factor infertility, as reported by The Journal of Urology 2, 3

The American Academy of Family Physicians and Human Reproduction Update recommend a second confirmatory semen analysis at least one month after the first to verify findings 1, 4
Endocrine evaluation is strongly indicated due to severe oligospermia, including serum testosterone and follicle-stimulating hormone (FSH) levels, as recommended by the American Academy of Family Physicians and The Journal of Urology 1, 2, 5
A complete reproductive history should be obtained, including duration of infertility, previous fertility, childhood illnesses, systemic illnesses, sexual history, and medication use, as recommended by the American Academy of Family Physicians 1, 3

Physical examination should focus on testicular size and consistency, presence of varicocele, and presence and consistency of vas deferens and epididymis, as recommended by the American Academy of Family Physicians and The Journal of Urology 1, 2, 4
Karyotype testing is recommended for males with sperm concentration <5 million/mL, and Y-chromosome microdeletion testing should be considered due to severe oligospermia, as reported by The Journal of Urology 2, 3

The combination of severe oligospermia and poor motility significantly reduces chances of natural conception, and management options may include treatment of underlying causes, referral to a reproductive endocrinology and infertility specialist, and discussion of assisted reproductive technologies (ART), as recommended by the American Academy of Family Physicians and The Journal of Urology 1, 2, 3
Lifestyle modifications, such as avoiding excessive heat exposure, smoking cessation, and weight management, should be discussed, as reported by Human Reproduction Update and The Journal of Urology 3, 6
The female partner's fertility status must also be evaluated concurrently for comprehensive infertility management, as recommended by the American Academy of Family Physicians and Human Reproduction Update 1, 4

Sperm morphology is a key component of semen analysis that provides important information about sperm quality and fertility potential 7
The World Health Organization (WHO) reference limit for morphologically normal forms is 4.0% (range 3.9-4.0%), meaning that even in fertile men, the majority of sperm have some morphological abnormalities 7

Sperm morphology alone cannot definitively distinguish between fertile and infertile men, as it is just one component of the overall semen analysis 8
Abnormal morphology may be associated with reduced DNA integrity 8
Abnormal morphology may be associated with potential DNA fragmentation 8

Confirm findings with a second semen analysis at least one month after the first to account for biological variability 9
Environmental exposures should be considered in the complete reproductive history 9
Hormonal evaluation including Luteinizing hormone (LH) may be relevant 8
If sperm concentration is also abnormal, consider genetic testing, including Karyotype analysis 7
If sperm concentration is also abnormal, consider genetic testing, including Y-chromosome microdeletion testing 7

Weight management if applicable may be beneficial for addressing modifiable risk factors 10
Antioxidant supplements may be considered to reduce oxidative stress, though evidence from high-quality RCTs is lacking 8

Concurrent evaluation of the female partner is essential, as infertility often involves multiple factors 9
Sperm DNA fragmentation testing may provide additional information about sperm quality beyond morphology 8
