In couples experiencing infertility, male factors account for approximately 30–40% of cases, representing a significant contributor to reproductive challenges. Male fertility generally refers to a man’s ability to impregnate his partner and is primarily determined by sperm count, motility, and morphology. Changes in male fertility can be subtle, yet it is equally important as female fertility.
Scientific Assessment Indicators for Fertility
- Routine Semen Analysis:This is the foundational evaluation.
- Sperm Concentration:According to the World Health Organization (WHO) 5th edition standards, the lower reference limit for normal is 15 million sperm per milliliter.
- Sperm Motility: The proportion of progressively motile sperm should be ≥ 32%, and total motility ≥ 40%.
- Sperm Morphology:A proportion of normal-shaped sperm ≥ 4% is considered indicative of potential normal fertilization capacity.
- Advanced Testing:Considered when routine analysis is abnormal or the cause is unexplained.
- Sperm DNA Fragmentation Rate: Assesses the integrity of genetic material. A fragmentation rate > 30% may be associated with fertilization failure and increased miscarriage risk.
- Seminal Plasma Antioxidant Capacity: Measures the semen’s ability to counteract oxidative damage.
- Endocrine and Genetic Testing: Includes sex hormone assays and chromosomal analysis.
Main Influencing Factors
The spermatogenesis cycle lasts approximately 70–90 days, meaning current health status directly impacts future sperm quality.
1. Lifestyle Factors
- Local Heat Exposure:Activities such as saunas, hot baths, prolonged sitting, or placing laptops on the lap may suppress sperm production.
- Smoking, Alcohol, and Drugs:Smoking clearly impairs sperm quality. Excessive alcohol consumption disrupts hormonal balance. All kinds of recreational drugs can harm reproductive health.
- Nutritional Status:Deficiencies in zinc, selenium, folic acid, and vitamins C, E, and D may affect sperm production and DNA stability.
- Stress and Sleep:Chronic stress and insufficient sleep can interfere with endocrine function.
2. Medical and Physiological Factors
- Varicocele:A common correctable cause.
- History of Infections:Genital tract infections may cause obstruction of the vas deferens or generate antisperm antibodies.
- Endocrine Disorders:Such as hypogonadotropic hypogonadism.
3. Genetic Factors
Such as Klinefelter syndrome or Y chromosome microdeletions.
Improvement Strategies
1. Basic Lifestyle Adjustments
- Wear loose underwear to avoid prolonged high temperatures in the scrotal area.
- Increase intake of vegetables, fruits, nuts, and seafood in the diet.
- Maintain a body mass index (BMI) in the normal range (20–25) and engage in regular exercise.
- Completely quit smoking, limit alcohol, and avoid exposure to environmental toxins.
2. Targeted Nutritional Supplementation
Under professional guidance, consider supplementing:
- Multivitamins containing zinc, selenium, and folic acid.
- Antioxidants such as vitamins C and E.
- Juvenex AOS18’s core formula, AOS18, is a unique blend of various active sugars extracted from seaweed and Reco18, combined with extracts of flaxseed oil, ginseng, goji berries, and raspberries, refined and blended using enzymatic extraction technology. The ingredients enhance antioxidant capacity, regulate the reproductive internal environment, and make sperm more viable and easier to absorb.This all-natural formula contains no artificial colors, flavors, sweeteners, or preservatives. It provides targeted nutrition to support sperm health and male fertility.
3. Medical Interventions
- Etiological Treatment: Such as surgical correction of varicocele.
- Assisted Reproductive Technologies: Depending on the situation, options include intrauterine insemination (IUI) or intracytoplasmic sperm injection (ICSI).
Conclusion
Male fertility can reflect overall health status. It is recommended that couples planning pregnancy have the male partner begin health management at least 3 months in advance. Joint fertility assessment by both partners helps identify issues and develop effective plans. Through scientific evaluation and targeted interventions, semen parameters can be improved in the majority of men.
