Female sexual function is cyclical: during the first about 11-13 days the egg cell maturation period takes place, followed by ovulation of the egg (this takes about 1-2 days when the egg may be fertilized), then the last stage of the menstrual or menses period: then the matured but unfertilized egg cell with bleeding is excreted through the female vagina.

The menstruation is the detachment of the endometrium each month (28 days on average, but this time period, shows quite large variation by individuals, or even at the same individual also, so is practically 25 to 33 days) and depletion accompanied bleeding.

•After menstruation the follicle stimulating hormone (FSH – follicle-stimulating hormone) levels begin to rise slowly, helping new follicle maturation.
• Around the middle of the cycle, estrogen levels begin to rise, which will soon be followed by the luteinizing hormone (LH) surge volume (in the graph it is called spike), which causes the rejection of the mature egg.
•The egg enters the fallopian tubes, the ruptured follicle develops into the corpus luteum, which produces the progesterone in the rest of the cycle, until menstruation. During this period, there is the greatest chance of fertilization.
• Meanwhile, the endometrium thickens and becomes richly vascularized and glandular, preparing for the embedding of the fertilized egg (zygote).
• If this does not occur, the corpus luteum degenerates, the production of progesterone stops and detachment of the mucous membrane starts, accompanied by bleeding.
• During ovulation, in the sexually mature female body  one egg matures (sometimes two, resulting in the birth of dizygotic twins.
• The lining of the uterus, the endometrium thickens continuously. After ovulation, the uterine wall changes (muscles get relaxed), and it is able to receive the fertilized egg for pregnancy.

Pay attention to these during menstruation!

Sensitivity, irritability, fatigue, cramps and pain. The monthly bleeding is not mentioned in connection with the accompanying                                                                                pleasant symptoms.

In addition the cycle has some less, or not at all detectable effects, for example for the vaginal pH. Even at the age of adolescence a normal lactic acid bacteria flora develops in the vagina, which plays a role in protecting against sexually transmitted diseases, and the more frequent vaginal infections regardless of sex life. Which habits increase vaginal infections, e.g. the risk of the most common bacterial vaginosis?

  • Ignoring the use of a tampon, which is considered comfortable at night should be an important part of hygiene during menstruation. The tampon closed into the vagina all night can work as a bacterial culture media so it can lead to a bacterial imbalance or bacterial vaginosis. The symptoms most commonly appear after menstruation.
  • Sexual intercourse during menstruation semen – compared to the vagina due to its alkaline pH it further reduces the number of lactobacilli, increasing the chances of vaginal infection.

The vaginal PH value, tips for maintenance for optimal PH value:

Almost every woman has experienced vaginal infection, which embittered their lives. The pH change is responsible for a portion of the complaints.

Vaginal secretion in healthy women is characterized by PH falling between 3.8-4.2. Above  4.5 PH value is usually a sign of infection. During menstruation, pregnancy, after giving birth, menopause, the vaginal PH changes in post-operation periods and its bacterial composition as well.

PH varies with age and during the cycle as well.
The pH- value of vaginal fluid of adult females is the highest preceding and during the menstruation periods, about 6.6, and the lowest is in the middle of the cycle, the value is 4 to 4.2). This is one of the very fortunate solutions of the nature, the more acidic (lower pH value), medium provides serious protection against infections.

The pH of the vaginal secretion is determined by gynecologists using a test strip. They take samples with an appropriate tool, they apply the sample on the test paper and after a few seconds the actual pH value can be determined by decimal precision.

Here are some ways to protect the value of the vaginal Ph:
1. Alkalizing is not good for the vagina.
2. In order to keep the optimal acidic pH of the vagina it is very important to follow basic hygiene rules such as the use of toilet paper from front to back, or hand washing before and after using the toilet.
3. The vagina should not be washed even with clean water. The alkaline soaps are even more dangerous, the shower gels, since with all these the acidic defense of the vagina can be neutralized. Using water or liquid detergent the strictly necessary bacterial flora of the vagina which keeps it healthy can be removed. It is the best not to interfere with the protective vaginal system, the acidic environment ,which is created by the lactic acid bacteria, the so-called lactobacilli is the most effective protection against fungal and other infections. You can use intimate wash however, because they reinforce the acidic line of defense, but they can only be applied externally.

4. Avoid rinse! It was in serious controversial disputes for a long time, ie. vaginal rinse. There is no scientific evidence that healthy women need it. The experts still believe that rinsing is unnecessary, because the vagina naturally keeps itself clean.
