Can Thyroid Gland Impact Your Fertility?
The second most prevalent endocrine disorder in women of reproductive age is thyroid illness. Significant links between thyroid conditions and anomalies of the reproductive system have now largely been established. Primary hyperthyroidism and hypothyroidism in both males and females have both been well-documented to cause varying degrees of gonadal dysfunction (oligomenorrhea, amenorrhea, lack of sperms or infertility). The hypothalamic-pituitary-thyroid axis and the hypothalamic-pituitary-gonadal axis interact to modulate neuroendocrine controls over reproductive processes in both hyperthyroidism and hypothyroidism. Thyroid hormones may cause changes in the male reproductive hormonal environment that lower testosterone levels and worsen the quality of sperm. All aspects of reproduction are impacted by thyroid disorders because they play a role in the regulation of the menstrual cycle and the development of infertility by interfering with the actions of the follicular-stimulating hormone (FSH) and luteinizing hormone (LH) on the steroid biosynthesis by specific triiodothyronine (T3) sites on oocytes.
