News | How Minerals Affect the Menstrual Cycle and Female Fertility
In a recent review published in Nutrients, researchers in Austria discussed the roles of certain minerals in the female reproductive system. The review shows that the relationship between minerals, female fertility, and menstruation is complex and highlights the link between diet and female fertility.
Overview of female reproductive regulation
Hormones play a vital role in human reproduction, regulating menstruation, ovulation, fertilization, and pregnancy. They promote follicular maturation and ovulation while supporting the endometrium to provide favorable conditions for a fertilized egg. The ovaries are central to female reproductive health, producing eggs for fertilization and synthesizing hormones such as estrogen and progesterone. During the follicular phase, increased gonadotropin-releasing hormone (GnRH) promotes the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). During the luteal phase, GnRH secretion decreases as progesterone levels rise.
Oxidative stress can damage cellular structures and may affect fertility. Excess iron, selenium deficiency, zinc deficiency, insufficient magnesium intake, and copper imbalance can all indirectly affect female fertility.
Effects of mineral intake on female fertility
Zinc
Zinc is essential for hormone production, endometrial function, and fertility. It regulates the production of LH, FSH, and steroids while protecting eggs from free-radical damage caused by oxidative stress. Zinc-finger proteins support estrogen receptor function, making adequate zinc levels important for fertility. Zinc deficiency may cause abnormal LH and FSH synthesis, impaired ovarian growth, menstrual irregularities, and hypertensive disorders of pregnancy.
Selenium
Selenium is essential for producing selenoproteins, which convert thyroxine into its biologically active form, triiodothyronine (T3). Thyroid metabolism is vital for maintaining hormonal balance in the female reproductive system because both hyperthyroidism and hypothyroidism can disrupt the menstrual cycle and conception. Maintaining optimal selenium levels is therefore important for consistent, effective ovulation.
Iodine
Iodine is essential for thyroid function and hormone production and interacts with reproductive hormones such as estrogen and progesterone. Iodine deficiency may cause hypothyroidism, infertility, and reproductive abnormalities. Adequate iodine intake is important throughout the menstrual cycle. Animal studies have shown that Lugol's iodine treatment may improve fertility in cows with unexplained infertility.
Iron
Iron is a key component of hemoglobin and is essential for oxygen transport by red blood cells and normal physiological activity. Iron deficiency may cause anemia, reduced egg quality, and less frequent ovulation. Maintaining adequate iron levels is important for women trying to conceive because low iron may contribute to infertility. In contrast, excess iron may reduce the number of eggs retrieved during assisted reproductive treatment.
Calcium
Calcium is important to the female reproductive system because it affects bone health, hormone release, and sperm-egg fusion. Calcium release prompts the pituitary gland to release LH and FSH, promoting ovarian production of estrogen and progesterone. Calcium indirectly affects hormonal regulation by altering ovulation and ovarian function. Balanced calcium levels are also essential for optimal cell division and embryo implantation.
Magnesium
Magnesium is essential for hormonal balance and female fertility. It supports enzymes such as aromatase, which converts androgens into estrogens. Magnesium is involved in the activity of about 600 enzymes, including those involved in DNA repair and glutathione metabolism. It may also improve insulin sensitivity and reduce comorbidities. Its antioxidant properties indirectly support fertility by protecting the body from oxidative damage, preserving egg quality, regulating ovulation, and supporting endometrial health.
Copper
Copper is essential for protecting the body from oxidative stress because it acts as a cofactor for superoxide dismutase. Copper affects antioxidant systems, signaling, and gene expression. However, excess copper may promote oxidation and impair endothelial function.
Manganese
Manganese is a valuable trace mineral that acts as a free-radical-scavenging antioxidant, protecting cellular structures from oxidative stress and potentially supporting female reproductive health. Oxidative stress damages egg function and quality, disrupting the hormonal regulation of female fertility.
Conclusion
Minerals play vital roles in female fertility, particularly in hormonal regulation, ovulation, oxidative stress, and endometrial health. Minerals such as selenium, calcium, and zinc are important during the follicular phase and ovulation. In contrast, excess iron, zinc deficiency, insufficient magnesium intake, and copper imbalance can indirectly affect female fertility.
