adolescence,time of life from onset of puberty to full adulthood. The exact period of adolescence, which varies from person to person, falls approximately between the ages 12 and 20 and encompasses both physiological and psychological changes. Physiological changes lead to sexual maturity and usually...
Today, sheep farmers in the Western Mediterranean de-season their ewes to achieve autumnal births. This strategy contrasts sharply with spring lambing further north, and provides benefits in terms of out-of-season availability of animal products. These c
Adolescents with an earlier onset of puberty were heavier in childhood and had an earlier timing and faster weight gain velocity in late adolescence. The intensity of adolescent weight gain was positively associated with adult BMI and fat mass index (FMI) in females. Early timing of adolescent BM...
Puberty is a stage of dramatic biological change that enables organisms to become physiologically capable of reproduction (Bronson and Rissman, 1986; Forbes and Dahl, 2010). Dispersal of an animal from the birthplace or natal group (i.e., natal dispersal) is an important event that often occur...
Rather, puberty also involves a set of neurobiological changes that are critical for the social, emotional, and cognitive maturation necessary for reproductive success. The primary goal of this paper is to broaden the research base and dialogue about adolescent romantic and sexual development, in ...
Therefore, the first child usually was born shortly after the onset of puberty, almost always dying during childbirth because of the physical immaturity of the mother.(114) When attempts to outlaw child marriage were made in 1929, nine volumes of testimony were published by the Age of Consent ...
However, we did not have data before the age of six. Future studies could also include data from before age 6 to verify this. Second, previous studies have found that puberty is an important factor in the development of brain structure [58,59,60], but this study was unable to examine ...
our data suggest that exposure to ATZ during the developmental period leads to a delay in reproductive maturity or the onset of puberty in mice, a reduction in primordial oocyte numbers and a decrease in oocyte stockpiles in adulthood. We cannot, however, exclude the possibility that the defects...
With the onset of puberty, there are changes in innate circadian rhythms that lead to a delay in the habitual timing of sleep onset [2]. As school start times are not correspondingly later, this leads to a reduction in the time available for sleep and is consequently thought to contribute ...
