Could Your Lifestyle Be Causing Infertility?

Could Your Lifestyle Be Causing Infertility?

In the age of instant gratification, infertility can feel like a diagnosis that will never be overcome for many couples wanting to be pregnant NOW. More than five million people of childbearing age in the United States, or one in every ten couples, have problems with infertility. Infertility is defined clinically as not being able to achieve and maintain pregnancy after one year of having regular, well timed, unprotected intercourse, or after six months if the woman is older than 35 years old. According to the NIH, 9% of men and 11% of women of reproductive age in the United States have experienced fertility problems. Studies suggest that 12%-15% of couples are unable to conceive after one year of unprotected sex, and 10% still have not had a live-born baby after two years. Female and male factors account for 40% of infertility each, and 20% of infertile couples have both female and male contributing factors. In ten percent of infertility cases, there is no identifiable cause for a pregnancy to not occur.

The Age Factor: End All Be All?
Couples trying to conceive before the age of 30 are between 40%-60% able to become pregnant within the first three months of trying. When women reach 30 years old, they are about half as fertile as their 20-year-old counterparts. This strongly suggests age is a major factor concerning fecundity, the ability of a couple to become pregnant in any given cycle. Women and men both see a decline in their fertility after the age of 35. Male fertility decline is more gradual though. Due to the finite number of eggs a woman is born with, about 1 million to 2 million, female fertility has an end point that will be reached, while men can continue to make sperm throughout their life. When menarche is reached, the onset of menstruation at puberty and the beginning of a woman’s fertile period of life, only 25% (about 200,000-400,000) of a woman’s eggs remains. The average woman will be down to only about twenty-five thousand remaining eggs at the age of 37. Woman only cycle an average of 451 times in a lifetime and while thousands of eggs degrade each month, only one usually matures to be released during ovulation.

A decline in the number and quality of female eggs can lengthen the time it takes to become pregnant in older women. This often results in an infertility diagnosis after six months for a woman 35 years or older. Considering fecundity decreases as we age, a longer time to conceive naturally is expected as we age. Male sperm quality and quantity also decline as men age, making it more difficult for sperm to reach and fertilize an egg. Aside from the natural decline of fertility as we age, there are other factors that increase in occurrence with increasing age and contribute to a further loss of fertility; uterine fibroids, tubal disease, endometriosis, genetic abnormalities, erectile dysfunction, decrease in testicle volume, and enlarged prostate.

Can you become pregnant in advanced reproductive age? Yes, but it can take much longer than if pregnancy is attempted earlier in life. Does this make the term “geriatric pregnancy” any less offensive? NO!! Let’s take a moment and appreciate the wonderful things our bodies can do as we age without labeling it with terms that make us cringe and think less about ourselves. Understanding it may take more rigorous approaches, effort, and time to conceive in our late 30s or beyond can ease the stress often felt by this age group.

Causes of Infertility
Non-age related causes of infertility are many and can be multi-factorial. Both the female and male partner’s reproductive and overall health needs to be addressed when identifying the reason a couple is falling short on becoming pregnant.

Female Factors: Failure to ovulate, menstrual cycle problems, structural problems of reproductive system, infection, failure of an egg to mature properly, implantation failure, endometriosis, polycystic ovary syndrome (PCOS), primary ovary insufficiency (POI), uterine fibroids, and autoimmunity.

Male Factors: Chromosome defects/disorders, diabetes, hyperprolactinemia, testicle injury, androgen insensitivity, infection, thyroid problems, undescended testicles, varicocele, blockage of transport tubes, vasectomy, erectile dysfunction, and retrograde ejaculation.

Lifestyle Factors: Nutrition, weight, exercise, sleep, physical and mental stressors, environmental and occupational exposures, substance abuse, and medication.

Other Factors:

  • Obesity: lower sperm count, increase risk of PCOS
  • Underweight: ovarian dysfunction, absence of ovulation
  • Excessive exercise: reduced sperm count, anovulatory cycles (not ovulating)
  • Tobacco/Alcohol/Marijuana/Illegal drugs: reduces male sperm production and embryo implantation
  • Stress: increases glucocorticoids that directly decrease testosterone in testes and brain of men, and inhibit gonadotrophin releasing hormone (GnRH) in women

Exposure to organic pollutants and endocrine-disrupting chemicals (EDCs) like PCBs and TCCD dioxin affect fecundity:
According to the NIH, “EDCs alter the function of the hormonal system, a key component in fertility. The LIFE study found that the EDC methyl paraben affects fertility in women, while phthalates and the UV filter benzophenone-2 affects fertility in men.”

Infertility Evaluation
With six months to a year already behind most couples before seeking evaluation for fertility, it is vital to assess both partners. Female and male evaluation is crucial before identifying the most effective treatments. There is nothing more crushing for a couple to spend months and months treating a “probable” female cause, when a semen analysis on the male partner has never been done. Remember, 40% of infertility is a male partner issue, with another 20% male and female combined issue. Therefore 60% of the time the male partner may need treatment.

Female evaluation will include a detailed history of health, cervical health history (abnormal Paps, LEEP procedures, cone biopsy), and mental/emotional assessment. Included in the initial screening will be a physical exam and blood tests. Functional testing such as the DUTCH test can offer insight into many causes of infertility with a few samples of dried urine. The gold standard in functional fertility testing, it looks at multiple facets contributing to infertility, such as sex hormones, stress hormones and toxic burden markers. Additional testing may be ordered if baseline testing indicates a deeper investigation is needed.

The “test de jour” for infertility is anti-mullerian hormone (AMH). A lower AMH level indicates decreased ovarian reserve. Recent studies show AMH may be less accurate though with Vitamin D deficiency. The CDC reported in 2011 that 50% of women ages 19-50 were insufficient in Vitamin D, and 23% were deficient. Antral follicle count is another test to detect ovarian reserve using trans-vaginal ultrasound to determine the number of follicles in each ovary. Studies show that decreased ovarian reserve is associated with fewer eggs available, but does not change the ability to get pregnant. However, it may be more difficult to conceive. This point is very important to make when considering the fear many woman experience when told AMH and AFC numbers are low.

Male evaluation will include a similar detailed history of health, testicular health/injury, occupational exposure, and mental/emotional assessment, along with a physical exam and blood tests. A semen analysis is critical to avoid lengthy and often unnecessary testing and treatment of the female partner.

Fertility Treatment

1. Timing!!!
Sound obvious? According to an Albert Einstein College of Medicine 2019 study, only 20% of women knew they were fertile 3-6 days out of a month’s cycle, and 16% of woman in the study believed they were most fertile during their menses. Timing is essential because an egg is only fertile for 12-24 hours after being released from the ovary. Sperm can survive in the female reproductive tract for up to 5 days, so the fertile window is considered 5 days before and one day after ovulation.

Teaching woman their body’s ovulation prediction kit (OPK) helps remove uncertainty about “well-timed” intercourse, and allows the physician to rule out timing as the issue. The body’s OPK consists of cervical position, cervical fluid, and basal body temperature (BBT). A study in the journal Fertility and Sterility found women who checked their cervical fluid consistently were 2.3 times more likely to get pregnant over a six-month period. BBT charts help maximize conception, predict ovulation (or lack thereof), and rule out various endocrine-related issues.

Quick tip: Avoid lubricants during intercourse due to their ability to impede the movement of sperm. Use Pre-Seed brand as a sperm friendly lubricant. Better yet see a practitioner to improve your cervical fluid. Cervical fluid quality can indicate hormonal imbalances.

2. Lifestyle Factors
Lifestyle factors should always be addressed by your practitioner BEFORE more advanced interventions. A Lancet study showed man who ate organic had 43% more sperm. Another study concerning stress and infertility, showed women with a support group have higher conception rates (54%) than those without a support group (20%). Lifestyle factors are often not considered as important as hormonal, ovulatory, or sperm abnormalities, but lifestyle is often the cause of those abnormalities.

3. Nutritional Therapies

Folate 400-800 mcg/day is essential for proper cell growth, metabolism, and neural tube development. Methylfolate and folinic acid are other natural occurring forms of folate that may be better depending on your genetics and how you process folate in the body.

CoQ10 50-300 mg/day has antioxidant and mitochondrial energy production effects, and significant improvements in sperm motility, concentration and morphology.

NAC 1200mg/day in divided doses helps improve egg quality, cervical fluid, prevent miscarriages, and acts as an anti-oxidant and anti-inflammatory.

Inositol 4g per day improves insulin sensitivity, egg quality and ovulatory function, decreases serum androgens, and increases sperm concentration.

Zinc 20-30 mg/day supports fertility by regulating normal hormone function, cell division, ovulation, and sperm production. An estimated 25% of Americans are deficient in zinc. High zinc foods include oysters, beef, egg yolks, oats, Brazil nuts, pumpkin seeds, carrots, beets, and cabbage.

Vitamin B6 30-50 mg/day helps to normalize many symptoms associated with a woman’s cycle. Vitamin B6 is involved in estrogen metabolism and can easily become depleted if estrogen dominance is a problem. Vitamin B6 possesses “progesterone-like effects” and has been shown to reduce estrogen while increasing progesterone levels.

Vitamin C 1,000-3,000 mg or higher raises progesterone, improves sperm morphology, and acts as an antioxidant to remove oxidative stressors.

Vitamin D 1,000-5,000 IU/day is able to control the genes involved in making estrogen. Vitamin D controls several genes involved in embryo implantation. Poor Vitamin D status has been associated with certain pregnancy complications such as gestational hypertension and diabetes.

Melatonin 3mg/day at bedtime increases number of mature eggs, and has anti-oxidant functions.

DHEA 25mg three times/day increases ovarian function and reserves and AMH levels, and lowers miscarriage rate. High rate of negative side effects are often experienced at this dose.

Acetyl L-Carnitine 1-3g/day improves sperm motility and morphology.

4. Botanical Medicine
Botanical Medicine is very effective in helping improve hormone levels, regulate menstrual cycles, ovulatory disorders, and implantation issues.

Vitex agnus-castus 1mL tincture in the morning can increase progesterone and restore ovulation.

Asparagus racemosa 2-4 mL tincture two to three times/day improves cervical fluid, libido and low sperm count.

Tribulus terrestris 200-400mg standardized extract supports sperm health and count, and ovulation induction and can increase DHEA levels.

Withania somnifera 1-4 mL tincture three times/day increases sperm motility and count, decreases stress factor hormones, and regulates menstrual cycle.

5. Body Therapies

Abdominal Mayan Massage improves circulation to reproductive organs, reduces scar tissue, and realigns tipped positioned uterus.

Acupuncture has been shown to improve numerous parameters involving fertility status.

Castor Oil Packs can improve infertility caused by fallopian tube dysfunctions, pelvic floor congestion, poor circulation and toxin accumulation.
