Women typically change the amount of produced hormones. This is due to the specific phase of the menstrual cycle:

  • The follicular. The beginning refers to the 1st day of menstruation and the end – to the formation of the dominant follicle, that is, about 14 per day.
  • Ovulatory. This includes a period of 3 days after the release of the dominant follicle with the egg. It 14-16 hours a day.
  • The luteal. Includes the time from ovulation until the next menstrual period, i.e. from 16 to 28 days.

The ratio of FSH and LH

Before the onset of puberty the balance of FSH and LH is equal to the ratio of 1:1. As they grow older, this proportion gradually acquires the value 1:1,5, that is, the amount of luteinizing becomes larger. This ratio remains in the normal state of health until the onset of menopause – normal FSH in women is less than the amount of LH is about 1.5 times.

Hormone Number, mked/ml
Follicular Ovulatory Luteal
FSH 3-10 10-46 1,4-7
LH 2-15 24-151 2-16

The hormone progesterone

Number, nmol/l
Women between 18 and 90 years
Follicular Ovulatory Luteal Menopause
0,3-2,2 0,5-9,4 7,0-56,6 Less than 0.6
1 trimester 2 trimester 3 trimester
8,9-468,4 71,5-303,1 88,7-771,5


Hormone Number, PG/ml
Follicular Ovulatory Luteal Menopause Pregnancy
Estradiol 57-227 127-476 77-227 19,7-82 Changes from 210 to 26 960

Norma testosterone in women

In the analysis of the hormone testosterone in women examines 2 types: total and free. The first indicates the level of this substance is associated and not associated with the transport protein. On the latest indicator free testosterone. The total level is equal to 0.26 and 1.3 ng/ml free testosterone is not dependence with the phase of the cycle, and with the age of the woman.

Hormone Number, PG/ml
Up to 20 years 20-39 years 40-59 years Over 60 years
Testosterone Of 0.13 to 3.09 Of 0.13 to 3.09 0,13-2,6 0,13-1,8


The permissible level of the hormone prolactin is determined by the clinics individual practices, so even the units are different. In General, the normal number is 4 to 33 ng/ml the Number of changes in each specific phase of the cycle of menstruation. For pregnant women it is normal when the hormone prolactin is high: its value can range from 34 to 386 ng/ml, and increasing it gradually with the development of the fetus.

The hormone DHEA

The acronym DHEA is hiding the name «steroid hormone dehydroepiandrosterone». In women it is produced in the ovaries, but only in the amount of 5%. The rest are synthesized by the adrenal glands. To age of 35 years, the level of this substance changes from 2660 to 11200 nmol/l In each trimester hormone blood women should show the following values of DHEA:

  • in 1 – 3,12-12,48 nmol/l;
  • in 2 – 1,7-7,0 nmol/l;
  • in 3 – 0,86-3,6 nmol/L.
