This study evaluated the association between use of misoprostol and other drugs to induce menstruation, and congenital anomalies. A sample of 4,856 pregnant women 20 years and older were enrolled consecutively in prenatal services in the Unified National Health System, in six Brazilian State capitals. Data on socio-demographics and use of medicines were obtained using an interview from the 21st...

OBJECTIVES Sex hormones affect physical, mental, and social health, yet their role in mediating social effects on aging is understudied. To facilitate such analyses with the National Social Life, Health & Aging Project Wave 2, we summarize the conceptual background, collection protocols, laboratory assays, and data analysis strategies for biologically active (free) levels of testosterone, estra...

The pineal gland is known to play a central role in the photoperiodic control of reproduction in seasonal breeders. The present review, based on experimental data obtained in four different species of hamster, the Syrian or golden, the Djungarian or Siberian, the Turkish and the European, attempts to evaluate the role of the pineal in this phenomenon, the message which is conveyed from this gla...

Gender differences in pain perception have been reported in literature. However, most such studies have ignored the role of female sex hormones in influencing pain response across menstrual cycle (MC). In this study, we have investigated the variation in pain response on different days of the menstrual cycle. Ninety subjects (60 females) were subjected to experimental pain of cold pressor task,...

Gonadal steroid hormones exert permanent organisational effects on the developing brain and thereby direct adult hormonal responsiveness to dictate sex-specific behaviour and physiology. Considerable progress has been made in elucidating the cellular mechanism of action of androgens and oestrogens during the perinatal sensitive period during which organisation occurs. This review highlights the...

Humans rely on internal representations to solve a variety of spatial problems including navigation. Navigation employs specific information to compose a representation of space that is distinct from that obtained through static bird’s-eye or horizontal perspectives. The ability to point to on-route locations, off-route locations, and the route origin illustrates the unique types of spatial kno...

In the present study we evaluated the effect of sex hormone on the generation of murine cytotoxic T cell responses. We show that the in vitro CTL response was strongly inhibited by progesterone but not by E1, E2 or testosterone. Our experiments attempting to understand the mechanism of the hormone action on CTL development have revealed that the ability of the cells to generate helper signals w...

There is much evidence to suggest that gender is an important factor in the modulation of pain. Literature data strongly suggest that men and women differ in their responses to pain: they are more variable in women than men, with increased pain sensitivity and many more painful diseases commonly reported among women. Gender differences in pharmacological therapy and non-pharmacological pain int...

Many important psychological characteristics show sex differences, and are influenced by sex hormones at different developmental periods. We focus on the role of sex hormones in early development, particularly the differential effects of prenatal androgens on aspects of gender development. Increasing evidence confirms that prenatal androgens have facilitative effects on male-typed activity inte...
