Physiology of the female puberty
Hormonal & physical changes
![Page 6: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/6.jpg)
I- During childhood Low levels of hormones (gonadostat):
GnRH
FSH&LH
Estrogen
![Page 7: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/7.jpg)
Suppression of the Activity Levels of Hormones
Hypersensitivity of the Hypothalamus Intrinsic CNS inhibition
![Page 8: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/8.jpg)
II- During Adolescence Increase levels of hormones:
Adrenal androgen (Adrenarche)
Gonadotrophic hormones (FSH&LH)
Estrogen (Gonadarche)
![Page 9: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/9.jpg)
High Activity Levels of Hormones Decrease sensitivity Maturation of Hypothalamus
Increase amplitude & frequency of pulsative GnRH
![Page 10: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/10.jpg)
The Release of Pulsative GnRH Increase Gonadotrophic & steroids Appearance of secondary sexual
characteristics Menarche Ovulation (estradiol-LH)
![Page 11: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/11.jpg)
Secondary Sexual Characteristics: Breast development Pubic and axillary hair growth Female fate distribution Vaginal and uterine growth Skeletal growth
![Page 12: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/12.jpg)
Growth
Growth spurt, express as increase linear growth velocity in cm per year.
![Page 13: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/13.jpg)
Growth Peak: 2 years after breast budding Height: reached maximum at age 17-18 years Skeletal changes:
* Insulin-like GF
* Growth hormone
* Sex steroid

Thelarche
The earliest sign of of puberty to become evident is usually breast growth
![Page 15: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/15.jpg)
Adrenarche
The growth of pubic and axillary hair is due to increase production of
adrenal androgen
![Page 16: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/16.jpg)
Adrenarche Increase androgen: 6-15 years Is not under control of the following:
* Gonadotrophin
* ACTH
* Prolactin

Tanner Staging
The breasts and of pubic hair growth of puberty have been classified into five stages

Gonadarche Factors which induce gonadarche in late pre-puberty:
* Anterior pituitary response GnRH
* Follicle reactivity to FSH&LH
![Page 20: Puberty Is the period which links the childhood and adulthood.](https://reader036.fdocuments.in/reader036/viewer/2022062714/56649d3a5503460f94a14aea/html5/thumbnails/20.jpg)
The Age of Menarche is decline: Improve nutritional status Body weight (47.8 kg) Percentage of fat (16-23%) Obese girls (23-30%)

In summary Puberty
Increase levels of gonadotrophins&steroids Appearance of secondary sexual characteristics Pulsatile GnRH (10-16 years) Central negative inhibition Maturation of positive feedback
