Hormones

What are hormones?

DotS the definition of hormones may vary. The (United States) Endocrine Society’s definition is:

Hormones–Made by endocrine glands, hormones are chemical messengers that travel in the bloodstream to tissues or organs. They affect many processes, including growth, metabolism, sexual function, reproduction, and mood”.2

The (Australian) Jean Hailes for Women’s Health’s (JH) definition is:

“Hormones are chemicals made in your body that relay messages through your bloodstream. For example, your hormones tell your body to eat and sleep”.3

Menopause

What causes menopause?

In What Causes Menopause? the JH explain:

“Menopause happens when your reproductive hormones change and there are no eggs left in your ovaries. Menopause can happen at the expected age, prematurely or early”.4

Menopause Hormones

What three hormones are of particular relevance at menopause?

In What Is Menopause? Hormones and Menopause the JH elaborate on:

“The three main hormones that change as you approach menopause are:

  • Oestrogen
  • Progesterone
  • Testosterone.

The change in hormone levels can lead to different menopausal symptoms”.5

Oestrogen

What is the role of oestrogen?

In Changes In Hormone Levels the North American Menopause Society (NAMS) elaborate on:

“As the primary “female” hormone, estrogen promotes the growth and health of the female reproductive organs and keeps the vagina moisturized, elastic (stretchy), and well supplied with blood”.6

Perimenopause

What is the association between perimenopause and hormones?

The JH explain:

“Your oestrogen production increases and decreases in the lead-up to menopause. As you approach your final period, your number of eggs decreases and oestrogen levels drop by up to 90%”.7

During perimenopause, does oestrogen decline in a nice neat regular fashion, getting less and less each month?

No. The NAMS note:Hormones

“Estrogen levels generally decline during perimenopause, but they do so in an irregular fashion. Sometimes there can be more estrogen present during perimenopause than in the past”.8

Progesterone

What is the role of progesterone?

The JH explain:

“Progesterone is responsible for things like mucus levels in your cervix, acidity levels in your vagina and milk cells in your breasts. It can also make you moody.

Progesterone is produced when an egg is released. It prepares your uterus for a fertilised egg and pregnancy. As you approach your final period, your progesterone levels decrease”.9

Testosterone

What is the role of testosterone?

The JH note:

“Testosterone is produced by your ovaries and other parts of your body.

You might think testosterone is a male hormone but it also plays an important role in women’s sexual desire, emotional wellbeing and bone and muscle strength.

Testosterone decreases gradually with age. In some women, levels fall by half between the ages of 20 and 40 years”.10

Polycystic Ovary Syndrome (PCOS)

HormonesWhat is Polycystic Ovary Syndrome (PCOS)?

DotS the definition of PCOS may vary. In Polycystic Ovary Syndrome (PCOS) the JH’s definition is:

“PCOS is a hormone imbalance that affects about one in 10 women. This condition is associated with increased levels of two hormones in the body – insulin and androgens (male-type hormones) – that cause symptoms such as absent or irregular periods, excessive facial and body hair, pimples, weight gain and challenges with fertility”.11

Health Care Provider

What if I need help with my hormones?

If you need help with your hormones, it may be in your best interest to choose to talk to your health care provider about this. Together you can clarify your signs and symptoms, discuss your options and if required, agree on who may be the most appropriate health care provider to help you.
