There is more and more evidence that Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years. The reduced production of Coenzyme Q10 cannot be compensated in any practical... More plays a physiological role in the maintenance of semen quality and male fertility [Alahmar 2021]:

Higher CoQ10 concentrations in seminal plasma correlate directly with elevated semen parameters such as sperm motility and sperm count.
Seminal CoQ10 concentrations are sub-optimal in male infertility conditions.

Pregnant woman — Infertility affects an estimated 15% of couples worldwide. Male infertility is a factor in about 50% of cases. The causes of male infertility are poorly understood, but there is evidence that oxidative stress is related to poor seminal fluid quality.

Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years.

More is a powerful antioxidantAntioxidants are substances that protect the cells and lipoproteins against the harmful effects of free radicals. They are substances that prevent the oxidation of other molecules and compounds. There are two broad categories of antioxidants: enzymatic and non-enzymatic. Non-enzymatic antioxidants are substances like Coenzyme Q10, vitamin C, vitamin E, glutathione, and various carotenoids. Prominent enzymatic antioxidants include catalase, glutathione peroxidase,... More, reducing levels of oxidative stress.

In a 2021 review article, Alahmar et al. [2021] summarize the research into CoQ10’s role in the regulation of male reproductive function:

restores semen parameters in male infertility patients
reduces the blood levels of biomarkers for oxidative stress
improves pregnancy and assisted reproductive technology outcomes
reduces sperm DNA fragmentation

CoQ10 Effects on Sperm Parameters

Alahmar et al. [2021] have reviewed several clinical trials of the CoQ10 supplementation of patients with male infertility. Overall, the outcomes of these studies show the following beneficial effects:

increased concentrations of Coenzyme Q10Coenzyme Q10 molecules are fat-soluble molecules that are both synthesized in the body and ingested in the diet and in supplements. Coenzyme Q10 is synthesized in the body in the same biological pathway as cholesterol. Bio-synthesis of Coenzyme Q10 begins to decline once humans reach their adult years.

enhanced sperm parameters: sperm concentration, motility, and morphology
improved oxidative stress bio-markers and increased protection against free radical-induced sperm damage

CoQ10 Effects on Sperm DNA Fragmentation

Current evidence shows that Sperm DNA Fragmentation plays a crucial role in male infertility. Oxidative stress may be the key mechanism causing the sperm DNA fragmentation. An excess of harmful free radicalsFree radicals are unstable and highly reactive molecules that are produced in the body during normal oxygen metabolism. Free radicals derived from oxygen are known as reactive oxygen species. Free radicals play both helpful and harmful roles in the body. Free radicals steal electrons from other substances in order to become stable. In so doing, the free radicals oxidize those... More may be causing kinks and breaks in sperm DNA.

Storch bringing baby — Three meta-analyses show beneficial effects of CoQ10 supplementation on semen quality, semen quantity, and semen mobility. Here, a meta-analysis of studies of CoQ10 supplementation of women with infertility shows a significantThe outcome of a clinical trial is thought to have statistical significance, or to be statistically significant, if the outcome is likely not caused by chance at a given statistical significance level, typically at the 0.05 level. Statistically significant outcomes may or may not be clinically significant. More effect on clinical pregnancy rates.

A meta-analysis of five randomized controlled clinical studies (n=449 infertile women) has shown that CoQ10 supplementation increases clinical pregnancy rates compared with placebo treatment or no treatment. The CoQ10 supplementation significantly increases clinical pregnancy rates both overall and in infertility subgroups such as the poor ovarian response subgroup (n=286) and the polycystic ovarian syndrome subgroup (n=163) [Florou 2020].

All study participants were women of reproductive age (mean age 33 years) diagnosed with either poor ovarian response or polycystic ovary syndrome. All were attending an assisted reproductive technology clinic [Florou 2020].

Safarinejad, M. R. (2009). Efficacy of Coenzyme Q10 on semen parameters, sperm function and reproductive hormones in infertile men. The Journal Of Urology, 182(1), 237–248.

Researchers enrolled 212 infertile men with various sperm abnormalities. Half of the patients were randomly assigned to receive 300 milligrams of Coenzyme Q10 daily, and half took matching placebos for 26 weeks. The researchers then continued to follow the patients’ progress for a 30-week treatment-free phase.
