What factors influence puberty
Answers
Answer:
Gonadotrophic hormones influence puberty.
Answer:
The ovaries of a young girl start functioning around the age of 10 to 14 years. It starts releasing the ova (ovulation) and this stage in her life is known as puberty.
At about the same time as the first ovulation, the ovary also releases female sex hormones into the bloodstream. These hormones, called as oestrogens, are responsible for bringing about bodily changes such as growth of mammary glands, widening of hips, growth of hair in the pubic region and armpits and an increase in the size of uterus and vagina. These developments are referred to as secondary sexual characteristics. While another hormone secreted by the corpus luteum, progesterone prepares the uterus for receiving the embryo.
In boys, puberty takes place around the age of 11 to 15 years of age. The testes start producing testosterone, resulting in the development of secondary sexual characteristics like deepening of voice, growth of testes and penis, growth of hair on chest, in the pubic region, armpits, chin and upper lips (moustache).
