Exercise with inadequate caloric intake suppresses thyroid hormone conversion (low-T3 syndrome) as energy preservation response. Study of 27 untrained women at 70% aerobic capacity found abrupt T3 reduction (16%) and fT3 reduction (9%) between 19.0 and 25.0 kcal/kg lean body mass, and fT4 increase (11%) and rT3 increase (22%) between 10.8 and 19.0 kcal/kg. Increasing energy availability to 25 kcal/kg LBM without reducing exercise may prevent athletic amenorrhea.

Hypothyroid men have lower libido, lower sperm count, higher prolactin, and twice the prevalence of clinical hypogonadism (13.8% vs 6.5%); mechanism involves T3-mediated STAr protein expression in Leydig cells limiting cholesterol transport for testosterone synthesis; T3 addition to T4 therapy improves sexual desire in biochemically euthyroid men with persistent symptoms.

Hypothyroid men have lower libido, lower sperm count, and higher prolactin; they are twice as likely to have clinically low testosterone. T3 enhances testosterone biosynthesis via STAr protein expression in Leydig cells. Correcting hypothyroidism can double testosterone and halve prolactin. Subclinical hypothyroidism (TSH 4.5–10) also causes sexual dysfunction. Adding T3 to T4 therapy improves sexual desire.

Enterosgel, a polymethylsiloxane polyhydrate enterosorbent, may increase live births in women with endometritis when combined with antibiotics and probiotics. Endotoxin lowers progesterone and elevates PGF2α, increasing abortion risk; Enterosgel absorbs endotoxin. A study of 98 patients showed live birth rates of 6/32 with antibiotics alone, 19/33 with antibiotics plus Enterosgel, and 30/33 with antibiotics plus Enterosgel plus probiotic.

TRH increases blood pressure, resting pulse, and prolactin, which can lower testosterone and progesterone. TRH rises when thyroid hormones are low and stimulates TSH. When the thyroid does not adequately respond, TRH remains elevated.

Weight loss resistance occurs when extreme calorie deficit suppresses thyroid hormone conversion and resting metabolic rate. Low energy availability abruptly reduces T3 and fT3, and increases fT4 and rT3 at specific thresholds. Increasing energy availability restores thyroid function and can reverse athletic amenorrhea without reducing exercise.

Hypothyroidism lowers pregnenolone and downstream steroid hormones (DHEA, testosterone, estrogen) with implications for mood, mental illness, reproduction, libido, dementia risk, substance abuse, aging, appearance, and muscle mass. StAR protein shuttles cholesterol into mitochondria to make pregnenolone; thyroid hormone T3 regulates StAR. Study shows serum ADIOLS, ADIOL, DHEAS, DHEA, and pregnenolone sulfate are decreased in hypothyroidism. Embedded quoted account lists hormones derived from pregnenolone.

DHEA (dehydroepiandrosterone) declines 2-3% annually starting in late twenties; by 40, individuals have 50% of peak levels; by 70, 10-20%. DHEA is the precursor for testosterone, estrogen, and 50+ other hormones. Decline (adrenopause) causes fatigue, reduced recovery, declining libido, muscle loss, mood changes. Journal of Clinical Endocrinology study: DHEA supplementation in adults over 40 improved bone density, skin thickness, sexual function, and wellbeing within 6 months; improvements reversed upon cessation. Recommended dose: 25mg daily for women, 50mg for men, taken in morning. Cost approximately $8 for 3-month supply ($0.09/day).
