How this protocol works
In plain language
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:
- Ovulation disorders (PCOS, thyroid issues)
- Tubal blockage or damage
- Endometriosis
- Uterine abnormalities
- Age-related egg quality decline
Male factors:
- Low sperm count or motility
- Abnormal sperm shape
- Hormonal imbalances
- Varicocele
- Lifestyle factors
WHEN TO SEE A SPECIALIST:
- After 12 months trying (under age 35)
- After 6 months trying (over age 35)
- Known fertility risk factors
- Irregular or absent periods
LIFESTYLE FACTORS that affect fertility:
- Healthy weight (both partners)
- No smoking
- Limited alcohol
- Reduced stress
- Regular exercise (moderate)
- Healthy diet
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.
