Reports outline hyperthyroidism study results from Wageningen University.(Report)
"The objective of this study was to determine whether dietary-induced mild fetal/neonatal hyperthyroidism influenced the initiation of spermatogenesis and the development of the adult-type Leydig cell population. Previously, the effects of neonatally induced hyperthyroidism have been investigated in rats using rather high doses (5 to 10 mu g/100 g body weight) of tri-iodothyronine, which not only influenced testicular development, but also negatively affected the general body condition of the animals," scientists in Netherlands report (see also Hyperthyroidism).
"To induce hyperthyroidism the diet of the dams was supplemented with 15 mu g thyroxine (T-4)/100 g body weight 2 weeks prior to mating and the dams and their offspring were kept on this diet until sacrifice. Pups were killed between days 7 and 64 after birth. At the age of 12 days plasma thyroid-stimulating hormone (TSH) levels tended to be lower in hyperthyroid pups, and from the age of 15 days onwards plasma TSH levels were significantly lower in hyperthyroid animals. Concomitantly, plasma T-4 levels were significantly elevated. From the age of 12 days onwards, plasma follicle-stimulating hormone levels were lower in hyperthyroid animals compared with age- matched control groups. Sertoli cell differentiation did not seem to be influenced by the mild hyperthyroid condition, as no difference in tubule lumen formation was observed between euthyroid and hyperthyroid animals. Nevertheless, a small effect on the progression of spermatogenesis was observed 15 days after birth, as the most advanced type of germ cells in the control testis were ...
