Invertebrate Neuropeptides and Hormones: Basic Knowledge and
Recent Advances, Transworld Research Network (Ed.) (2007) 19, 2007 Hormonal processes along with enzymatic processing similar to that found in vertebrates occur in annelids. Amino acid sequence determination of annelids precursor gene products reveals the presence of the respective peptides that exhibit high sequence identity to their mammalian counterparts. Furthermore, these neuropeptides exert similar physiological

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders
Andrology, EarlyView.Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Andrology, EarlyView.Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

Andrology, EarlyView.Abstract Background Cryopreservation causes sperm injury and the success of surgical sperm retrieval (SSR) for azoospermic men is just over half depending on the cause of azoospermia. The role of autologous platelet‐rich plasma (PRP) in male factor infertility (MFI) is unclear. Objective To conduct a systematic review of the role of PRP in MFI focusing

Season of birth and variations in male reproductive health: A population‐based cohort study
Andrology, EarlyView.Abstract Background Season of birth has been associated with various later reproductive health outcomes in women, but little is known on the potential associations in men. Objectives To investigate the association between season of birth and semen characteristics, testes volume and reproductive hormone levels in young men.
