Where is testosterone made?
About 95% of a man’s testosterone is produced in the testes by specialized cells called Leydig cells. A small amount comes from the adrenal glands. Healthy testicular function is the primary driver of normal testosterone levels.
Do fatty acids play a role?
Yes. Testosterone is made from cholesterol, and dietary fats help supply the building blocks and support the cell membranes involved in hormone production. Balanced intake of essential fats—especially omega-3s and certain omega-6 fatty acids—supports healthy steroid production, while trans fats and extreme imbalances may impair it.
Does blood flow matter?
Absolutely. Proper blood flow delivers luteinizing hormone (LH), cholesterol, oxygen, and nutrients to the testes, and carries testosterone into circulation. Reduced circulation can limit testosterone output even if the cells themselves are functional.
Can fatty acids be absorbed through scrotal skin?
Scrotal skin is highly permeable compared to other areas of the body, and lipophilic (fat-soluble) compounds can pass through it. However, absorption depends on formulation, concentration, and individual skin factors. Time of day may have a minor effect, but consistency and proper application matter more.
Icelandic Lamb Tallow vs. Beef Tallow
Icelandic lamb tallow naturally contains stearic acid, conjugated linoleic acid (CLA), and essential fatty acids that support cholesterol availability and cellular membrane health. Compared to beef tallow, lamb tallow is typically softer and more unsaturated, which may improve spreadability and skin absorption.
While both are sources of saturated fats, grass-fed lamb fat tends to have a more favorable fatty-acid profile. That said, testosterone production is influenced by overall health, hormone signaling, circulation, sleep, and body composition—not fat type alone.
