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.
