Is the Pineal a Chastity Gland?
I’m not heavily invested in my pineal gland, favoring more crucial parts of my brain and groin anatomy.

“Darkness activates the secretion of melatonin, inhibiting sexual development through a series of neuronal chains in the retina, hypothalamus, reticular formation, and the spinal cord.”

“The pineal gland also secretes norepinephrine and contains significant concentrations of hypothalamic peptides such as luteinizing hormone-releasing hormone (LHRH), thyrotropin-releasing factor and somatostatin. Pinealocytes also contain tryptophan hydroxylase and aromatic amino acid decarboxylase, which are involved in the synthesis of serotonin. Increase of cAMP evokes augmentation in serotonin N-acetyltransferase activity that is followed by increased pineal glandular activity and production of melatonin, and eventual inhibition of reproductive development.”
Ironically, the pineal gland is known as the “penis of the brain.”
Melatonin lowers sperm count and lessens sperm motility.

“In 1994 A.V. Sirotkin found that melatonin inhibits progesterone production but stimulates estrogen production, and it’s widely recognized that melatonin generally inhibits the thyroid hormones, creating an environment in which fertilization, implantation, and development of the embryo are not possible. This combination of high estrogen with low progesterone and low thyroid decreases the resistance of the organism, predisposing it to seizures and excitotoxic damage, and causing the thymus gland to atrophy.”
Yalin was the first name given to melatonin by Aaron B. Lerner (1920-2007) when he discovered it at Yale.
