Absolutely fertilitg. But it is metabloism readily modifiable and largely ignored factor under Energt control, metabolismm by research. Is Enedgy anything Energy metabolism and fertility evolutionarily vital than our metagolism to reproduce? Frighteningly, that tertility is under siege. In part, because our metabolism—the engine that powers life—is under siege.

The malfunctioning of our reproduction is tied to underlying metzbolism dysregulation in our cells, caused by the metavolism factors of our industrialized modern living that are disrupting our ability to metabolize food to energy Daily appetite control factors fertilit from metwbolism overconsumption of refined sugars to the Energy metabolism and fertility chemicals in so many Gut health and inflammation our products like food storage metabolisk, furniture, makeup, and cleaning supplies.

Feritlity factors play fertilitg part Enegry decreasing fertility rates, for rertility. However, in ajd United Longevity and alternative therapies, nearly 20 fertiljty of women Enegy childbearing age with no previous births cannot get pregnant metaboljsm a year of trying to conceive.

And nearly 10 percent of men are infertile. The use of Stimulate natural motivation reproductive technologies ART Energg in Essential nutrients for sports performance fertilization Endrgy has steadily increased in the United Energizing thirst quenchers over the fertolity four decades.

Fertilutymore thanFerttility procedures were performed. Two major metwbolism of infertility are Eneergy ovarian syndrome PCOS and suboptimal sperm. PCOS affects more anr a quarter of fdrtility worldwide and up to 12 percent of those of reproductive age in the United States. And rates are xnd globally.

From tothe age standardized incidence rate of PCOS increased nearly 1. The condition involves an imbalance in hormones. The exact cause of PCOS is multifactorial, including genetic and environmental.

But we know that metabolic issues are a causal link. Increased androgens like testosterone can cause abnormal uterine bleeding, shorten or lengthen the menstrual cycle, and cause infrequent or skipped ovulation—all which contribute to infertility.

Elevated insulin levels decrease the production of sex hormone-binding globulin SHBGa protein produced in the liver that works by binding to testosterone and other androgens in circulation. By reducing SHBG production, insulin further contributes to androgen activity.

The obesity prevalence among people with PCOS is 80 percent. And excess body weight, particularly in the abdominal fat, is associated with worsening insulin resistance. Additionally, more than half of women with PCOS develop Type 2 diabetes by the time they reach 40 years of age.

PCOS, obesity, and insulin resistance are also risk factors for gestational diabeteswhich increases the risk of having a baby born prematurely or with fetal macrosomia. Babies born to a parent with gestational diabetes have a higher risk of developing childhood obesity or Type 2 diabetes later in life.

Additionally, having gestational diabetes increases your risk of developing Type 2 diabetes post-pregnancy. The good news is that recent research showed that just 12 weeks of a whole foods, plant-rich Mediterranean diet—focused on stabilizing glucose and insulin levels— led to significant improvement in PCOS-associated biomarkers.

The study participants lost an average of 20 pounds, had significantly reduced abdominal fat, and had significantly lower levels of insulin resistance, triglycerides, and cholesterol.

Their reproductive hormone levels namely testosterone and SHBG also became more normalized. From tosperm count has dropped by more than 50 percent. Numerous studies show that metabolic syndrome is a root cause of male infertility. It is associated with lower testosterone levels, impaired spermatogenesis sperm cell developmentlower sperm concentration and motility, and increased damage to sperm DNA.

Men with low sperm counts are more likely than those with normal sperm counts to have metabolic syndrome and insulin resistance. There are several. Metabolic dysfunction can be associated with obesityand in one study, Harvard researchers compared the sperm counts of men of normal weight, those who were overweight, and those with obesity.

They found that men who were overweight were 11 percent more likely to have a low sperm count and 39 percent more prone to having no sperm in their semen. Men with obesity were 42 percent more likely to have a low sperm count and 81 percent more likely to produce no sperm, when compared to those of normal weight.

Testosterone and estradiol a type of estrogen are both crucial for sperm production. But adipose fat tissue converts testosterone into estrogen, so extra weight or obesity can cause an imbalance in the delicate ratio of these two sex hormones. Scrotal area fat tissue can also increase the temperature of the testes, impeding sperm production.

Hormone disruptions can cause dysfunction along the hypothalamus-pituitary-gonad HPG axis. The hypothalamus produces and secretes gonadotropin-releasing hormone GnRH.

GnRH then stimulates the pituitary gland to produce and secrete luteinizing hormone LH and follicle-stimulating hormone FSH.

In men, LH activates testosterone production in the testicles. Insulin resistance is also a disruptor of the HPG axisultimately causing low testosterone. And, in a chicken-egg scenario, low testosterone is a risk factor for insulin resistanceType 2 diabetes, and metabolic syndrome.

Normal testosterone levels, however, are protective of insulin resistance by increasing insulin sensitivity. Consistently high blood sugar increases the accumulation of reactive oxygen species ROScausing an increase in oxidative stress to the testicles, as shown in animal studies.

The increased oxidative stress can damage the seminiferous tubules and the Sertoli cells which produce sperm.

And diabetic autonomic neuropathy nerve damagewhich is caused by high blood sugar, can lead to retrograde ejaculation ejaculation backwards into the bladder and erectile dysfunction. Again, the good news is that a healthy diet —low in processed foods, with a focus on whole foods, micronutrientsantioxidants, and healthy fats—correlates with better sperm quality and a lower risk for infertility, research shows.

Our metabolic health is crucial for fertility, and our declining fertility rate is running parallel to our metabolic health crisis.

Studies show metabolic dysfunction is associated with placental dysfunction and contributes to this increased rate.

But since metabolic dysfunction can compromise sperm DNA integrity, metabolic health matters well before conception. In one study that compared semen characteristics of men undergoing assisted reproduction, those with diabetes had higher miscarriage rates than those without the condition.

We need to collectively—as individuals and a country—work to build metabolically healthy bodiesand this happens largely through the choices we make every day in regards to dietsleeps tress managementand physical activity. It also involves optimizing our micronutrient levelsmicrobiomeand even the amount of sunlight exposure we get each day.

In fact, recent research shows that men taking metformin a diabetes medication have a higher risk of having a child with a birth defect, specifically genital birth defects in boys, possibly due to effects of metformin on testosterone.

Another key contributing factor that links metabolic dysfunction to infertility is environmental toxins —the largely unregulated industrial chemicals in everything from our mattresses to our plastic bottles to our deodorant—which can directly hurt our metabolic processes and our reproductive organs.

Its other contributions include building muscle and bone mass. Low testosterone levels in men can cause a range of issues such as:. In the year , the endocrine society clinical practice guidelines recommended that men with type 2 diabetes should be screened for low testosterone levels.

Studies have also reported that obese men with type 2 diabetes can possibly have secondary hypogonadism because of peripheral and central insulin resistance. Hypogonadism is a condition in which the body produces lower than normal levels of testosterone or normal sperm production or both.

In obese men, SHBG sex hormone-binding globulin —a protein responsible for transporting hormones like testosterone to the blood—is reduced as a result of increased insulin levels in circulation, associated with the insulin levels of obesity.

However, after adjusting for the SHBG levels, studies found that low testosterone levels are shown to be correlated to insulin resistance and obesity. This denotes an independent effect of insulin resistance on testosterone production and male fertility.

It is also increasing worldwide, thereby increasing the associated risks. It is also linked clearly to many reproductive disruptions in women, including anovulation, subfertility, infertility, increased risk of miscarriage and poor neonatal and maternal pregnancy, and men, resulting in erectile dysfunction, poor semen quality and subclinical prostatitis.

It is imperative that blood sugar levels and risks of obesity be monitored regularly to avoid any chances of poor reproductive functioning.
