Temperature-dependent sex determination (TSD) was first reported in 1966 in a lizard. 1
Since that time it has been shown to occur in a wide variety of reptiles, including all …

In many reptile species, sexual differentiation of gonads is sensitive to temperature during a
critical period of embryonic development (thermosensitive period, TSP). Experiments carried …

Large numbers of apoptotic early diplotene oocytes were observed during the transition from
ovary-like undifferentiated gonadal tissue to testes during sex differentiation in presumptive …

The phenotypic sex of many teleost fishes including flounders can be experimentally altered
by treating embryos or larvae with varied temperatures or sex-steroid hormones. To analyse …

In many vertebrate species, sex is determined at fertilization of zygotes by sex chromosome
composition, knows as genotypic sex determination (GSD). But in some species—fish …

We have previously shown that hexarelin, a novel GH-releasing peptide (GHRP), is able to
elicit GH release when administered iv, sc or by mouth and that it is a more potent GH …

Channel catfish have an XX female‐XY male sex determination system. Although genetic
males of this species are readily feminized with exogenous steroid, the pattern of gonadal …

Leatherback (Dermochelys coriacea) and green (Chelonia mydas) sea turtles in Suriname
lay eggs over several months of the year. During this nesting season, changes in rainfall …

Apoptosis (programmed cell death) is important in normal biological processes and in
