The science is there people !!
It is possible to improve poor s***m parameters and improve your chances of falling pregnant.
I make sure to always have a s***m check done for my fertility patients. Part of the "leave no stone unturned" philosophy.
S***m quality has steadily declined over the past 50 years. Between 1973 and 2011, the global s***m concentration and total s***m count decreased significantly. This decline was most pronounced in Western countries, with a reduction in the total s***m count of almost 60%.
Marina Urbanietz’s August 2025 Medscape article, What Your S***m Says About You, offers a concise review of selected studies on how supplements and lifestyle can influence s***m parameters, drawing on a recent paper in a Nature journal.
Semen analysis not only provides information on fertility but also offers insights into the overall health. The cited paper reported that s***m quality can significantly improve with basic lifestyle and dietary changes.
The study, led by Hannah Lyons, a researcher at the Robinson Research Institute and School of Biomedicine at the University of Adelaide attributed the s***m count decline to multiple factors.
These include chronic conditions such as diabetes and metabolic syndrome, exposure to endocrine-disrupting chemicals such as phthalates, bisphenol A, cadmium, dioxins, and lead, and heat exposure.
Lifestyle factors, including certain medications, substance use, poor diet, and physical inactivity, can impair s***m production by disrupting hormonal regulation, damaging testicular cells, and increasing oxidative stress due to elevated levels of reactive oxygen species (ROS).
High ROS levels can damage s***m DNA, compromise the membrane integrity, and reduce s***m motility. Established risk factors include smoking, heavy alcohol consumption, drug abuse and excessive exercise.
S***m quality can recover more rapidly than previously believed. In a study of 132 men with fertility issues, a 3-month micronutrient regimen, including L-carnitine (440 mg), L-arginine (250 mg), zinc (40 mg), vitamin E (120 mg), glutathione (80 mg), selenium (60 µg), coenzyme Q10 (15 mg), and folic acid (800 µg), significantly improved semen parameters. Volume, s***m concentration, progressive motility, total motility, and morphology increased by 33.3%, 215.5%, 93.1%, 36.4%, and 23.0%, respectively (all P < 0.001). No improvements were observed in healthy individuals (n = 73).
In the 6 months following the intervention, the pregnancy rate among the partners of the participating men was also recorded. More pregnancies occurred in the intervention group (25.8%) than in the healthy group (15%). Although this study had some limitations, including age differences and limited risk factor data, two additional trials supported these findings. The researchers concluded that micronutrients may restore s***m production within 3 months.
A 2021 study by Markus Lipovac, PhD, also at the Robinson Research Institute at the University of Adelaide, and colleagues, evaluated 339 men who received the same micronutrient supplements along with lifestyle changes. These include a healthy diet, regular exercise, and reduced smoking and alcohol consumption.
Of these, 162 men received supplements and lifestyle guidance, whereas 177 followed lifestyle and dietary modifications. After 6 months, s***m DNA fragmentation index (DFI) and pregnancy rates were assessed. In the supplement group, DFI decreased from 10.48 to 6.51 overall and from 20.39 to 9.93 in men with DFI > 15% (P < .001). Pregnancy rates were higher with supplements: 27.78% vs 15.25% overall and 41.30% vs 22.86% in men with DFI > 15%.
The limitations of this study include missing demographic data, lack of randomisation, and lack of information on the extent of lifestyle changes.
Semen analysis may reflect the overall health of men, not just their fertility. Men with infertility or abnormal semen are at a higher risk for hospitalisation and early death. For example, men with infertility had a 26% higher risk for death (95% CI, 1.01-1.59), and men with oligo- or azoos***mia had a 67% higher risk (risk ratio, 1.67; 95% CI, 1.26-2.21) than those with normal s***m counts.
Abnormal s***m parameters often reflect poor health or disease and are linked to a higher risk for cancer. Studies have shown that men with infertility have an increased risk for prostate and testicular cancer.
