Kisspeptin is a high-purity research peptide supplied in a lyophilized powder format, intended exclusively for laboratory research and development applications. Manufactured to achieve purity levels above 99% and confirmed through precise HPLC and LC-MS analytical testing, this compound is packaged in a sterile, sealed vial to help ensure stability, reliability, and consistent integrity during storage and handling.
Vitamin D3 (VD3) is a pleiotropic hormone with diverse physiological functions, but its role during early embryonic development in fish remains poorly understood. This study investigated the effects of aqueous VD3 exposure on embryonic survival, hatching, and the expression of…
Objective: Kisspeptin-1 and Kisspeptin-54 are key regulators of the hypothalamic-pituitary-gonadal axis and may play a role in male reproductive function. This study aimed to evaluate the association between seminal plasma kisspeptin levels and male infertility, and to examine their relationships…
Background: Central precocious puberty (CPP) results from premature activation of the hypothalamic-pituitary-gonadal axis, causing early sexual development and related health risks. Stigmasterol (ST), a natural phytosterol with diverse pharmacological activities, has not been fully evaluated for CPP. Methods: This study…
Background: Reproductive and sexual dysfunction (uremic hypogonadism) are pervasive in maintenance hemodialysis (MHD) patients, yet the underlying neuroendocrine mechanisms remain poorly understood. Kisspeptin is the master upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis. We hypothesized that uremia-induced kisspeptin accumulation is…
This study examines how testosterone levels and kisspeptin gene expression are affected in male Syrian hamsters following pinealectomy and photoperiod modification. By examining the rhythmic changes in these parameters under long (16L: 8D) and short (8L: 16D) photoperiods, we aim…
The goal of this study is to see whether kisspeptin, a naturally occurring hormone, can stimulate the release of other reproductive hormones in women with hypothalamic amenorrhea (HA). The investigators are also examining whether kisspeptin can help women release eggs…
