B13-Female reproductive hormones Flashcards
What is ovulation.
At puberty eggs begin to mature and one is released
approximately every 28 days.
What is the acronym to remember the female productive hormones and which one is used first
FOlP
F- Follicle stimulating hormone (FSH)
O- oestrogen
L-luteinising hormone (LH)
P- progesterone
What female hormones are produced at the pituitary gland
Follicle stimulating hormone
Luteinising hormone
What female hormones are produced at the ovaries
Oestrogen
Progesterone
What is the function of follicle stimulating hormone
It causes an egg to mature
It stimulates the release of oestrogen
What is the function of oestrogen
Grows the lining of the uterus
Stimulates the release of Luteinising hormone
Inhibits follicle stimulating hormone’s
What’s the function of Luteinising hormone
Stimulates the release of an egg and progesterone
Inhibits oestrogen
What is the function of progesterone
Maintains the lining of the uterus during the second half of the menstrual cycle and during pregnancy
Inhibits both luteinising hormone and follicle stimulating hormone
What does oral contraception contain
hormones to inhibit FSH production so that no eggs mature
What do injection, implant or skin patch release
They slowly release progesterone to inhibit the maturation and release of eggs for a number of months or years
How does IVF treatment work
IVF = Vitro Fertilisation
1) IVF involves giving a mother FSH and LH to stimulate the maturation of several eggs.
2) The eggs are collected from the mother and fertilised by sperm
from the father in the laboratory.
3) The fertilised eggs develop into embryos.
4) At the stage when they are tiny balls of cells, one or two embryos
are inserted into the mother’s uterus (womb).
What are the disadvantages of IVF treatment
Low success rate or not always successful
Expensive
Stressful/emotional
Side-effects
