here are many recognised pros and cons to hormone replacement therapy – see the article on ‘What is HRT?’ for more information.
What happens if I have too little progesterone?
If progesterone is absent or levels are too low, irregular and heavy menstrual bleeding can occur. A drop in progesterone during pregnancy can result in a miscarriage and early labour. Mothers at risk of giving birth too soon can be given a synthetic form of progesterone to delay the onset of labour.
Lack of progesterone in the bloodstream can mean the ovary has failed to release an egg at ovulation, as can occur in women with polycystic ovary syndrome.
