Evaluate the role of chromosomes and hormones
research support for testosterone
social factors are ignored
reductionist
What is the research evidence for testosterone?
a link between increased testosterone and sexual behaviour was confirmed in a study by Christina Wang
gave 227 hypogonadal men testosterone therapy and found that there was improved sexual libido
How is research into chromosomes and hormones reductionist?
accounts that reduce gender to chromosomes and hormones
cognitive approach draws attention to schema
The psychodynamic approach would acknowledge maturation as a factor but point to the importance of childhood experiences
suggests that gender is more complex than its biological influences alone
Describe the role of hormones for gender
most gender development comes from hormones
hormones act upon brain development and cause the development of the reproductive organs
at puberty, an increase in hormonal activity causes the development of secondary sexual characteristics
males and females produce many of the same hormones but at different levels
Describe the role of chromosomes for gender
egg has an X chromosome
some sperm have X and others have Y
the Y chromosome carries a gene called ‘sex-determining region Y’, the SRY gene causes testes to develop
these produce androgens which are important for male development
Describe the role of Oxytocin for gender
women typically produce oxytocin in much larger amounts than men, particularly as a result of giving birth
stimulates lactation
reduces the stress hormone cortisol and facilitates bonding
oxytocin is released in large quantities during and after childbirth
the fact that men produce less of this hormone has fuelled the stereotype that men are less interested in intimacy and closeness within a relationship
evidence suggests that males and females produce oxytocin in roughly equal amounts during activities such as sex and kissing
