喜來芝 Shilajit × 男性不孕症（精子品質低下）
結論：安全性檢視中
獨立判讀為 C（薄弱證據）：男性不孕適應症在人體證據面僅有 Biswas 2010 一篇 open-label 無對照 n=28 寡精症 RCT（方法學上等同 case series），且唯一直接相關；Pandit 2016 雖為雙盲 RCT 但對象是 45-55 歲健康男性的睪固酮 surrogate，非不孕人群；無任何 SR/MA 針對 shilajit + 活產或臨床懷孕率，Morgado 2023 SR 也僅評為 late-onset hypogonadism「possibly effective」。

機轉合理且訊號方向一致為正向，但證據量與品質遠不足以支撐臨床推薦，Examine C 與我的判讀一致。

Clinical evaluation of spermatogenic activity of processed Shilajit in oligospermia
結論：After 90 days: spermia +37.6%, total sperm count +61.4%, motility +12.4-17.4%, normal sperm morphology +18.9% (all P<0.001); serum testosterone +23.5% (P<0.001), FSH +9.4% (P<0.05); seminal MDA -18.7% (lower oxidative stress). Hepatic/renal panels unchanged; no adverse effects.

Clinical evaluation of purified Shilajit on testosterone levels in healthy volunteers
結論：Vs placebo at 90 days, Shilajit significantly (P<0.05) increased total testosterone (reported +20.45%), free testosterone (+19.14%), and DHEAS (+31.35%); LH and FSH well maintained (no HPG-axis suppression). Surrogate endpoint for male reproductive health; no sperm parameters or fertility outcomes measured.

Do 'testosterone boosters' really increase serum total testosterone? A systematic review
結論：Most testosterone boosters fail to raise serum testosterone. Only beta-hydroxy-beta-methylbutyrate and betaine showed efficacy in male athletes. For Shilajit, authors conclude 'purified Shilajit extract (PrimaVie) can be considered possibly effective for men with late-onset hypogonadism' - graded as limited/possible evidence (not robust). No sperm or fertility endpoint conclusions for Shilajit.

Profertility effects of Shilajit on cadmium-induced infertility in male mice
結論：Shilajit dose-dependently reversed cadmium-induced declines in sperm count, motility, and normal morphology; restored serum testosterone and testicular antioxidant capacity; improved histology. Mechanistic/preclinical support only - not directly applicable to idiopathic human male infertility.

喜來芝（Shilajit）在台灣社群屬冷門題材，PTT 備孕版（GoodPregnan）、健身板（MuscleBeach）、Dcard 男性保養版、Mobile01 醫療保健版均查無針對『男性不孕症 / 精子品質』的真實使用討論串。備孕版鄉民提升精蟲只提肌肉鋅、左旋精胺酸、瑪卡、CoQ10，從未提及喜來芝；健身板補劑討論亦無此品。所有中文命中結果幾乎都是電商（Amazon、iHerb、蝦皮、BigGo 比價、港加保健品店）與近期才冒出的業配型 SEO 媒體，缺乏匿名鄉民實測與辯證，無法形成在地經驗共識。
