Effects of Hormones on Gender

There are two main sex specific hormones- androgens for males and oestrogen for females. Differences in the production of these hormones, as well as oxytocin, can have effects on development and gender differences.

Hormones

  • Hormones are chemicals that are secreted by glands in the body.
  • Hormones affect the way the body works and develops. They can act over a long or short period of time.

Oestrogen and androgens

  • There are two main sex specific hormones:
    • Oestrogen for females.
    • Androgens for males. Testosterone is the main androgen.

Hormone production

  • Generally speaking, men will produce more testosterone than females and females will produce more oestrogen than males.
  • Each sex will produce the other type of hormone, but in lower quantities.
  • Differences in the production of these hormones, as well as oxytocin, can have effects on development and gender differences.

Oestrogen

  • It is believed that sex hormones affect the brain and therefore cause gender differences in behaviour.
  • The effect of oestrogen on female behaviour has been studied. - Oestrogen, in some women, can lead to premenstrual tension (PMT).
  • Symptoms of PMT include headaches, cramps, clumsiness, tiredness, mood swings, depression and aggression.

Easteal (1991)

  • Easteal (1991) believed that PMT could potentially be the reason behind criminality in females.

Congenital Adrenal Hyperplasia (CAH)

Congenital adrenal hyperplasia (CAH) is a syndrome whereby more testosterone is produced than usual.

CAH

  • Congenital adrenal hyperplasia (CAH) is a syndrome whereby more testosterone is produced than usual.
  • It can occur in both sexes with different effects:
    • If men have CAH, they will have early sexual development but otherwise will not have much of an effect.
    • If females have CAH, the increased amounts of testosterone will cause the girls to become masculinised. They are generally more ‘tomboyish’.

Females with CAH

  • Girls with CAH generally prefer toys stereotypically meant for boys.
  • They are physically more masculine (deep voice, facial hair, wide shoulders).
  • Their growth rate is faster and puberty can happen earlier.

CAH and the female body

  • CAH can also cause ambiguous genitalia, meaning that it can be difficult to determine if they are male or female at birth.
  • Other symptoms include irregular menstrual cycle and potential fertility issues.

CAH and the brain

  • By studying individuals with CAH, scientists can better understand the role of sex hormones on development.
  • They believe that sex hormones affect the brain and therefore cause gender differences in behaviour.

Oxytocin

Oxytocin is produced by both males and females.

Oxytocin and gender

  • Oxytocin is produced by both males and females.
  • However the higher levels of oestrogen in females causes a different effect on the brain.
  • Therefore, females could potentially feel a bigger effect from oxytocin as compared to males.

Importance of oxytocin

  • Oxytocin is believed to have an important impact on:
    • Social recognition.
    • Bonding.
    • Attachment.

Rimmele et al. (2009)_

  • A study conducted in 2009 by Rimmele et al. discovered that higher levels of oxytocin in males improved their ability to recognise other people’s faces.
  • They did not know the faces beforehand.
  • Their ability to recognise objects and other non-social images did not improve.

Gender roles

  • The different responses to oxytocin has been used to potentially explain gender differences in roles.
  • For example, the role of the mother versus the father.
  • As oxytocin is released during labour to help aid labour and milk production, it also creates nurturing feelings.
