In this study, 100 patients showing hypothyroidism symptoms (64 female and 36 male), and 100 patients with hyperthyroidism (32 female,
and 68 male) were selected to investigate the effect of thyroid dysfunction on fertility compared with 10 healthy people of both genders.
Subjects were divided according to age and gender. Fertility hormones (Testosterone, LH, FSH, Progesterone, and Prolactin) were measured
to find the correlation between thyroidal dysfunction and fertility problems. Our finding showed that in females with hypothyroidism,
testosterone, LH, Prolactin, and progesterone were significantly reduced when compared with normal values, while in females with
hyperthyroidism, testosterone, LH, progesterone and prolactin were significantly changed among other hormones. In men with
hypothyroidism, prolactin was significantly affected, while in men with hyperthyroidism LH showed a significant change when compared
with normal. Moreover, total seminal count in male patients with both types of throiditis was significantly reduced when compared with
normal. This may as a direct correlation between thyroid dysfunction and fertility in both genders.
