Abstract In vertebrates, folliculogenesis and ovulation are regulated by two distinct pituitary gonadotropins: follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Currently, there is an intriguing consensus that a single hypothalamic neu

How has the genome duplication impacted the diversification of sexual characteristics in the teleost lineage? This study shows that androgen receptor ohnologs in medaka appear to have diverged in their roles for regulating morphological and behaviour

Abstract Generally, successful testis transplantation has been considered to require immune suppression in the recipient to avoid rejection of the transplanted tissue. In the present study, we demonstrate in medaka that allogeneic adult testicular ti

Junpei Yamashita et al. use a medaka model to evaluate how neurons in the preoptic area that express the neuropeptides, PACAP and VIP, regulate pituitary hormones. Their results suggest that estrogen helps maintain sex-dependent activity of these neu

Recent studies in mice demonstrate that a subset of neurons in the medial preoptic area (MPOA) that express galanin play crucial roles in regulating parental behavior in both sexes. However, little information is available on the function of galanin

Male and female animals display innate sex-specific mating behaviors. In teleost fish, altering the adult sex steroid milieu can effectively reverse sex-typical mating behaviors, suggesting remarkable sexual lability of their brains as adults. In the

Follicle-stimulating hormone (FSH) is a gonadotropin released from the pituitary essential for the regulation of folliculogenesis in vertebrates. Unlike mammals, the regulatory mechanism of FSH is unknown in teleosts because gonadotropin-releasing ho
