In keeping with the World Well being Group (WHO)’s Worldwide Committee for Monitoring Assisted Reproductive Expertise, infertility is a reproductive system illness characterised by failure to realize scientific being pregnant after 1 yr or extra of standard sexual activity with out utilizing contraception. In 8% of {couples} who’re unable to conceive, male infertility is the first trigger.1 In 35% of infertility circumstances, the issue might be traced again to each the female and male or to unknown causes.1 Lowered semen focus (indicating the variety of sperm), decreased semen quantity, elevated semen viscosity, poor sperm motility (a sign of how properly sperm transfer to fertilize an egg), vitality, and/or irregular morphology (the form and look of the sperm) are all diagnostic standards for male infertility, in keeping with the WHO’ Handbook for the Examination of Human Semen and Sperm-Cervical Mucus Interplay, 2010 version.2,3
The reason for male infertility is probably going multifactorial, however proof signifies that publicity to environmental toxins might play an essential position in its etiology. Analysis has established a relationship between sperm abnormalities and publicity to phthalates; chemical substances present in plastic meals containers; medical tools like IV tubing; shampoos, deodorants and different private care merchandise; and lots of different sources. Wang and colleagues discovered a correlation between semen phthalate metabolites and reduces in semen quantity, movement parameters, curvilinear and straight-line velocity, and a rise in share share of irregular sperm heads and tails.4 In an earlier examine, the identical researchers noticed larger urinary ranges of phthalates correlated with declines in sperm ranges and complete sperm depend.5 Greater urinary concentrations of phthalates have been additionally related to a better share share of irregular sperm heads.5 Different research have discovered a noteworthy constructive affiliation between urinary phthalate ranges and decreased sperm concentrations.6,7 Phthalates can alter DNA methylation,8 indicating that they’ve an epigenetic impact that may inflict injury on each present and future generations.
Benzene is one other chemical discovered to play a job in male infertility. Widespread publicity in the US happens attributable to benzene’s presence in cigarette smoke, gasoline fumes, and automobile emissions. A examine of males uncovered to benzene at work noticed a decline in complete sperm depend and sperm motility and a rise in irregular sperm morphology.9 One other examine of males occupationally uncovered to benzene famous an elevated incidence of chromosomally faulty sperm.10 De Celis and associates investigated sperm well being in employees uncovered to ethylbenzene, benzene, toluene, and xylene.11 In comparison with males who weren’t uncovered to those chemical substances, males who interacted with these toxins at work had alterations in sperm viscosity, liquefaction capability (the period of time required for sperm to liquify after ejaculation), sperm depend, sperm motility, and the proportion of sperm with regular morphology.11 A few of these abnormalities corresponded to the variety of years the lads have been uncovered to the chemical substances.
On this article I’ll current the case of an infertile man who was uncovered to environmental pollution. This case examine will exhibit how a proprietary fertility method for males, containing 27 vitamins, was in a position to overcome obstacles to conceiving in a affected person who refused to change his way of life to reduce toxin publicity. As clinicians, it illustrates the necessity to modify our therapies to accommodate the extent of compliance amongst our sufferers.
Case Research
Private Historical past & Considerations at Presentation
A 33-year-old male house-builder offered to my observe on June 6, 2017. He labored laborious performing bodily labor 5 to six days per week. He and his spouse had a 4-year-old baby and wished to conceive one other. He was unwavering in his consumption of the usual American weight-reduction plan and consumed 1 to 2 alcoholic drinks per evening. He loved fishing from a close-by river and consuming his recent catches. He was 40 kilos obese.
He and his spouse of 8 years arrived in my workplace after 2 years of unsuccessfully attempting to conceive a second baby. A collection of earlier checks carried out by an area fertility specialist had revealed that the reason for the couple’s lack of ability to conceive was male issue infertility. His spouse was keen to implement various approaches to conception, though he was reluctant to take action. He was not serious about altering his western weight-reduction plan, which can have been exposing him to toxins linked to infertility and was doubtless contributing to his obese, which in itself is a threat issue for decreased fertility.12 He was too drained to do extra train or pursue health. I educated him and his spouse about toxins that may act as hormone disruptors that will have an effect on female and male fertility.
Diagnostic Evaluation
The proof within the medical literature pointing towards a correlation between environmental toxins and infertility supplied a sound rationale for ordering an natural acids profile, in addition to an environmental pollutant panel that measures metabolites of a number of widespread environmental toxins. The affected person’s pollutant panel outcomes (Determine 1) confirmed excessive ranges of benzoate (>12.85; reference vary [RR]: <7.00) – an indicator of excessive toluene publicity. The marker tt-muconic acid was additionally elevated (0.45; RR: <0.17), indicating a excessive benzene publicity.
Determine 1. Environmental Pollution Profile

A sperm evaluation was additionally undertaken. Sperm focus was 9 million/mL (decrease reference restrict: 15 million/mL). Sperm motility was 42% (decrease reference restrict: 32%). Morphology was 5% (decrease reference restrict: > 4%). And semen quantity was 2 mL (decrease reference restrict: > 1.5 mL).
From 1999 to 2010 the WHO progressively decreased the decrease reference restrict for these parameters.13 Which means “regular” ranges of sperm well being indicators have been beforehand a lot completely different than at this time. For instance, the decrease reference restrict for sperm motility was beforehand 50%. Measurements larger than the decrease reference restrict don’t guarantee fertilization or a profitable being pregnant; slightly, larger measurements enhance the probability.
I additionally ordered a lipid panel, which revealed excessive complete ldl cholesterol, a excessive focus of low-density lipoprotein (LDL), a low focus of high-density lipoprotein (HDL), excessive triglycerides, and an elevated liver enzyme (ALT: 52; RR: 9-46). The elevated lipid ranges have been according to the findings of a examine that noticed infertile males having a better threat of cardiometabolic illness.14 His testosterone ranges have been inside vary (639 ng/dL; RR: 250-1100).
Therapeutic Intervention
As famous earlier, the affected person refused to change his weight-reduction plan or implement an cardio train routine. He was additionally unwilling to start a detoxing program to be able to enhance section 1 and a pair of liver detoxing. In section 1 detoxing, enzymes within the liver catalyze the oxidation, discount, and hydrolysis of poisons.15 In section 2, toxins are conjugated and in the end excreted from the physique (Determine 2).15
Determine 2. Hepatic Cleansing
Because of his refusal to undertake a detoxing program, I needed to modify my traditional protocol to fulfill the affected person on his personal phrases. With some negotiation and nudging by his spouse, he was keen to do 2 issues. First, as a easy manner assist detoxing, he agreed to enhance his bowel motion regularity. He started supplementation with magnesium citrate to extend his bowel actions from as soon as each 2-3 days to 2 instances per day. The purpose was to easily reduce reabsorption of poisons by way of section 3 detoxing from the gastrointestinal tract by rising regularity. I nonetheless maintain out that he’ll in the future pursue an intensive detoxing protocol.
Second, he was keen to take a complement formulated for male infertility. This product consists of 27 substances studied for his or her helpful results on sperm depend, focus, motility, morphology, and DNA integrity by defending sperm from the damaging results of oxidative stress. These substances embrace beta-carotene, vitamin C, bioavailable folate, pure vitamin E, zinc, selenium, L-carnitine, grape seed extract, coenzyme Q10 (CoQ10), lycopene, and N-acetylcysteine, to offer broad-spectrum antioxidant assist. Zinc is included to enhance sperm motility and scale back sperm DNA fragmentation.16 Selenium and vitamin E additionally enhance sperm motility along with morphology.17 Supplementation of those vitamins to infertile males has resulted in an elevated price of spontaneous being pregnant.17 L-carnitine improves sperm motility and elevates sperm depend.18 In keeping with a scientific evaluate of the medical literature, L-carnitine improves sperm high quality and will increase spontaneous being pregnant charges in {couples} affected by a low sperm depend.19 Arginine is included within the method as a result of it elevates ranges of nitric oxide, which is required for sperm high quality and erectile perform. Arginine has been proven to enhance sperm motility in males with infertility.20 Most of the substances within the method have been discovered to have synergistic results.
In a single examine, CoQ10 along with nutritional vitamins C and E led to considerably improved sperm counts and motility amongst 169 infertile males.21 CoQ10 supplementation mixed with the nutritional vitamins was related to a 28.4% conception price.21 Gual-Frau and colleagues studied 20 infertile males with grade I varicocele (a standard reason for low sperm depend and sperm high quality) who supplemented with L-carnitine, vitamin C, CoQ10, vitamin E, vitamin B9, vitamin B12, zinc, and selenium each day for 3 months.22 Supplementation was related to a 22.1% decline in sperm DNA fragmentation and an increase in complete numbers of sperm cells. Mora-Esteves and Shin discovered that supplementation of antioxidants by males with infertility who have been present process assisted replica led to a 4.85-fold enhance in live-birth price.23
It’s related to this case examine that a few of these vitamins are additionally required to assist section 1 of the liver’s detoxing pathways. B nutritional vitamins, folic acid, and nutritional vitamins E and C are all required for optimum detoxing by the liver.
Outcomes of Therapy
Six months after the initiation of the male fertility complement, the affected person’s semen parameters have been considerably improved (Desk 1). Sperm focus elevated from 9 million/mL earlier than supplementation to 58 million/mL after supplementation. Sperm motility elevated from 42% to 68% after supplementation. Sperm morphology improved from 5% to 10%. Semen quantity elevated from 2 mL to three.4 mL. 9 months after the affected person began the complement, his spouse turned pregnant.

Earlier than | After | |
Sperm focus | 9 million/mL | 58 million/mL |
Sperm motility | 42% | 68% |
Sperm morphology | 5% | 10% |
Semen quantity | 2 mL | 3.4 mL |
Dialogue
Infertility is a widespread downside amongst fashionable {couples}. There’s rising proof that toxins are concerned in each female and male infertility, in addition to hostile well being outcomes in newborns and youngsters uncovered to chemical substances in utero. The surge in autism and different childhood maladies, together with most cancers, is broadly attributed to toxin publicity within the womb and postnatally. These chemical substances not solely impair fertility; additionally they induce epigenetic modifications that may impression many generations.
Antioxidants are recognized to guard towards oxidative stress, which is induced by environmental toxins. For instance, phthalates have been proven in mice to trigger liver and kidney injury by way of oxidative stress, and the antioxidant vitamin E protected towards this injury.24 In a rodent examine, the antioxidants vitamin E and vitamin C decreased oxidative stress and improved spermatogenesis, which had been impaired by phthalate administration.25 And in mice uncovered to phthalates, L-carnitine maintained the sperm’s regular morphology and chromatin high quality and normalized the sperm depend, supporting the concept that nutrient supplementation can defend the sperm from environmental pollution.26 This may increasingly clarify, partly, antioxidants’ helpful results on sperm well being in a world the place males are frequently uncovered to dangerous chemical substances.
Within the case examine offered right here, a fertility complement containing antioxidants was related to profitable conception after 9 months of use. This success was achieved regardless of the actual fact the affected person was unwilling to alter his way of life in any manner. Since he had excessive ranges of metabolites of two widespread environmental pollution (benzene and toluene), it’s attainable that the success of the supplementation was attributable to a protecting impact of the vitamins towards these environmental toxins. This case examine illustrates the helpful results of antioxidants in male infertility. Moreover, it’s an instance of what clinicians can accomplish after we adapt our protocols to match a affected person’s compliance stage.
