TLDR
It is suggested that arecoline inhibits pineal–testis function in experimentally induced hypothyroid rats.
Abstract
Arecoline is known to cause endocrine dysfunction. In the current article role of arecoline on pineal-testis activity was investigated in hypothyroid rats induced by propylthiouracil (PTU). PTU treatment caused thyroid dysfunction ultrastructurally with a fall in T3 and T4 levels followed by a rise of thyroid stimulating hormone (TSH) level. Pineal activity was impaired by PTU treatment, as evident from degenerated synaptic ribbons and mitochondria of the pinealocytes with depletion of pineal and serum N-acetyl serotonin and melatonin levels. Leydig cell function was suppressed, evident from reduced smooth endoplasmic reticulum and depletion of testosterone level. Sex accessories function was impaired by showing scanty rough endoplasmic reticulum with depletion of fructose and sialic acid levels. Arecoline treatment that caused pineal dysfunction and testicular stimulation in control rats, suppressed both pineal and testis functions after PTU treatment. The findings suggest that arecoline inhibits pineal-testis function in experimentally induced hypothyroid rats.

TL;DR: AlA supplementation ameliorated the toxicity induced by hypothyroidism as illustrated by enhanced reproductive organ weights, testosterone, LH, and FSH levels, testicular steroidogenesis, and oxidative stress parameters.

Effect of hypothyroidism on the testes in mature rats and treatment with levothyroxine and zinc.

TL;DR: After treatment, testicular histology and spermatogenesis gradually recovered in all groups with hypothyroidism, but maximum improvement was achieved in the levothyroxine+zinc sulphate replacement group, indicating a possible role of zinc in testicular function.

Regulated hypothermia in the hypothyroid rat induced by administration of propylthiouracil

TL;DR: The regulation of Tc at hypothermic levels over a wide range of Ta values and when rats were housed in a temperature gradient indicates that chronic PTU induces a state of regulated hypothermia.

Ultrastructural interrelationship between the pineal gland and the testis in the male rat

TL;DR: Pinealectomy and orchidectomy caused hyperactivity in Leydig cells and pinealocytes, respectively, which suggests a mutual relationship between the pineal gland and testis in the rat.

Ultrastructural and hormonal modulations of the thyroid gland following arecoline treatment in albino mice.

TL;DR: Atropine (arecoline antagonist) injection prevented the changes (hyperactivity) induced by acute (40 min) arecline treatment, and atropine prevents thyroid dysfunction induced by arecoline.
