A decline in skeletal muscle mass is usually associated with sarcopenia, a prevalent disease observed in vulnerable elderly individuals. Additionally, different levels of estrogen associated with menstrual periods may regulate exercise performance in women. Therefore, estrogen is considered to play a crucial role in skeletal muscle homeostasis and motor ability, although the exact mechanism remains unclear. This suggests that estrogen plays a beneficial role in the recovery process after muscle recession. Based on the relevant literature, this paper discusses the impact of estrogen on skeletal muscle diseases and provides a review of recent research progress. The aim is to elucidate the role of estrogen in the treatment of postmenopausal skeletal muscle diseases and to propose possible future research directions and key scientific issues that must be addressed urgently. In this article, we reviewed the role of estrogen in postmenopausal skeletal muscle and outlined the proposed molecular mechanisms.
