The importance of estrogens in controlling brain and behavioral sexual differentiation in female rodents is an unresolved issue in the field of behavioral neuroendocrinology. Whereas, the current dogma states that the female brain develops independently of estradiol, many studies have hinted at possible roles of estrogen in female sexual differentiation. Accordingly, it has been proposed that a...

Background: Determination of sex is an important parameter other than age, race and stature during forensic identification crime scene investigation. Females tend to have finer denser ridges on their fingertips males. Present study aims at differentiating gender from fingerprint ridge density. Material Methods: This a cross sectional conducted March 2022 2023 in Nobel Medical College Teaching H...

Most amphibians lack morphologically distinguishable sex chromosomes, but a number of experimental techniques have shown that amphibian sex determination is controlled genetically. The few studies suggesting that environment influences sex determination in amphibians have all been conducted at temperatures outside of the range normally experienced by the species under study, and these effects p...

Sexual dimorphism in humans has been the subject of wonder for centuries. In 355 BC, Aristotle postulated that sexual dimorphism arose from differences in the heat of semen at the time of copulation. In his scheme, hot semen generated males, whereas cold semen made females (Jacquart, D., and C. Thomasset. Sexuality and Medicine in the Middle Ages, 1988). In medieval times, there was great contr...

aim and background: mood disorders are a significant group of psychiatric disorders. bipolar spectrum disorders are mood disorders that usually remain unrecognized and subsequently undertreated. one of the most useful screening instruments for underdiagnosed bipolar disorders is the mood disorder questionnaire (mdq). this paper presented the persian version and psychometric properties of mdq fo...

background: chromosome abnormality (ca) including sex chromosomes abnormality (scas) is one of the most important causes of disordered sexual development and infertility. scas formed by numerical or structural alteration in x and y chromosomes, are the most frequently ca encountered at both prenatal diagnosis and at birth. objective: this study describes cytogenetic findings of cases suspected ...

In Drosophila, we have found that some of the motor terminals in wandering third-instar larvae are sexually differentiated. In three out of the four body-wall muscle fibers that we examined, we found female terminals that produced a larger synaptic response than their male counterparts. The single motor terminal that innervates muscle fiber 5 produces an EPSP that is 69% larger in females than ...
