New to collagen? There is a guide in the encyclopedia. Read the guide → Studysummary In this animal study, researchers observed that both aging and lower androgen levels in male albino rats led to significant structural changes in meibomian glands, including reduced acinar cell size, diminished meibum secretion, and increased collagen deposition. Our plain-language summary of this paper — not a Tressless recommendation.
This study investigated the effects of age and androgen levels on the histological structure of meibomian glands in albino rats. Three groups of 10 adult male albino rats, aged 6 months, 1 year, and 2 years, were analyzed. The results showed that younger rats (group I) had normal acinar structures with abundant meibum vesicles and high levels of dehydro-epiandrosterone (DHEA) hormone. In contrast, older rats (groups II and III) exhibited a marked decrease in acinar cell size, reduced secretion of meibum vesicles, and increased collagenous fiber deposition. There was also a decline in androgen receptor immune reaction and androgen levels in the blood. The study concluded that both age and androgen levels significantly impact the structure and function of meibomian glands.
