“Estrogen levels generally decline during perimenopause, but they do so in an irregular fashion. Sometimes there can be more estrogen present during perimenopause…”.1

Umbrella
What may the Hormones Umbrella include?

Depending on the Source (DotS) this Umbrella may include:

  • Estrogen
  • Hormones
  • Oestrogen
  • Progesterone
  • Testosterone
  • Women’s Sex Hormones

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. They alert the body that it is time to do something. They help control many of the body’s functions, such as temperature, growth, energy, repair of cells, reproduction, sexual function and digestion. Hormones tell the body to eat, to stop eating, to sleep, to wake up, to grow, or – when hormone levels decrease – to stop growing”.3

Menopause

What three hormones are of particular relevance at menopause?

In About Menopause: Hormones & Menopause the JH elaborate on:

“The three hormones of particular relevance at menopause are:

  • Oestrogen
  • Progesterone
  • Testosterone”.4

Perimenopause

Is there an association between perimenopause and hormones?

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

“Many changes during the years leading up to menopause (perimenopause) are brought on by changing levels of hormones produced by the ovaries, mainly estrogen”.5

Perimenopause Oestrogen

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”.6

Estrogen and Oestrogen

What is the difference between estrogen and oestrogen?

I am guessing the difference between estrogen and oestrogen is DotS and/or DotC (Depending on the Country). It seems to me the term estrogen is used in the United States and Canada; and the term oestrogen is used in other countries. Or not.

What does oestrogen do?

The NAMS note:

“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”.7

Progesterone

What does progesterone do?

The JH explain:

“Progesterone, another natural female hormone, decreases towards menopause. This is because progesterone is produced only if an egg is released (ovulation). The release of progesterone usually prepares the uterus for a fertilised egg and pregnancy. With menopause, ovulation stops, and so progesterone levels drop”.8

Testosterone

Does testosterone decrease with menopause or age?

The JH note:

“Rather than its levels dropping suddenly or dramatically at menopause, testosterone decreases gradually with age. In some women, levels fall by half between the ages of 20 and 40 years.

There is still a lot to learn about testosterone, particularly about how it works in women and its impact on sexuality”.9

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.
