How This Protocol Works
Simple Explanation
Subfertility (reduced fertility) affects about 1 in 6 couples trying to conceive. It can be caused by female factors (ovulation problems, tubal issues, endometriosis), male factors (low sperm count/motility), or a combination. In many cases, no clear cause is found.
COMMON CAUSES:
Female factors:
Male factors:
WHEN TO SEE A SPECIALIST:
LIFESTYLE FACTORS that affect fertility:
* Folate is essential for both partners and critical for preventing neural tube defects.
* CoQ10 supports egg and sperm quality by improving mitochondrial function.
* Myo-Inositol is particularly helpful for women with PCOS.
* Zinc, Selenium, and L-Carnitine support male fertility.
* DHEA may help women with diminished ovarian reserve (use under medical supervision).
Expected timeline: Egg and sperm development takes about 3 months, so supplements should be started at least 3 months before trying to conceive. Effects may take several months to manifest.
Clinical Perspective
Subfertility: Failure to conceive after 12 months of regular unprotected intercourse. Evaluate female (ovulatory function, tubal patency, uterine anatomy) and male (semen analysis) factors. Female evaluation: menstrual history, FSH/LH/AMH, thyroid, prolactin, HSG or SHG, pelvic ultrasound. Male: semen analysis (count, motility, morphology). Common causes: ovulatory dysfunction (PCOS, hypothalamic), tubal factor, endometriosis, male factor, unexplained (30%).
CRITICAL: Full fertility workup for both partners before treatment. Address modifiable factors (weight, smoking, alcohol, stress). Supplements support but don't replace fertility treatment (ovulation induction, IUI, IVF). Some supplements specifically evidence-based for certain conditions (myo-inositol for PCOS, DHEA for diminished ovarian reserve).
* Folate (A-grade): Essential; neural tube defects. Systematic review: (PMID: 27450775). Cochrane: (PMID: 26096827). 400-800mcg methylfolate daily.
* Coenzyme Q10 (B-grade): Egg/sperm quality. Female meta-analysis: (PMID: 26597398). Male review: (PMID: 28458920). 200-600mg daily.
* Omega-3 Fatty Acids (B-grade): Hormone production; anti-inflammatory. Systematic review: (PMID: 27840029). 2-3g EPA+DHA daily.
* Vitamin D (B-grade): Reproductive hormones. Meta-analysis: (PMID: 28750270). 2000-4000 IU daily. Target 40-60 ng/mL.
* Zinc (B-grade): Sperm production; ovulation. Systematic review: (PMID: 26845419). 15-30mg daily.
* L-Carnitine (B-grade): Sperm motility. Cochrane: (PMID: 23597877). 2-3g daily (men).
* Selenium (B-grade): Sperm motility; thyroid. Meta-analysis: (PMID: 28558777). 100-200mcg daily.
* Myo-Inositol (A-grade): PCOS fertility. Meta-analysis: (PMID: 29549878). 2-4g daily. Improves ovulation, egg quality.
* Vitamin E (C-grade): Antioxidant. Review: (PMID: 27918887). 400 IU daily.
* DHEA (B-grade): Diminished ovarian reserve. Meta-analysis: (PMID: 29550478). 25-75mg daily. Under medical supervision.
Assessment targets: Semen analysis, hormone levels (FSH, LH, AMH, estradiol, testosterone), thyroid function, vitamin D, menstrual pattern.
Protocol notes: Timeline: gamete development ~3 months; start supplements 3+ months before conception attempts. Age: female fertility declines significantly after 35; don't delay evaluation. Male factors: contribute to 40-50% of cases; always evaluate. PCOS: myo-inositol first-line supplement; may restore ovulation. Diminished ovarian reserve: DHEA, CoQ10, growth hormone in IVF setting. Antioxidants: oxidative stress affects both egg and sperm; CoQ10, vitamin E, selenium. Endometriosis: omega-3, NAC may help; primarily surgical/medical treatment. Unexplained: empiric treatment with supplements reasonable; may try IUI or IVF. Prenatal vitamins: recommend comprehensive prenatal for women. Caffeine: moderate intake (<200mg) likely fine. Alcohol: avoid during conception attempts. Weight: both under and overweight affect fertility; optimize BMI. Thyroid: optimize TSH <2.5 for conception. Male lifestyle: heat exposure, smoking, excessive alcohol harm sperm. Stop harmful supplements: high-dose vitamin A, certain herbs may be harmful.
