ovula.jpgOvulation

Ovulation (ovum - egg), an exit of mature ovum, capable to fertilisation from an ovary follicle in a belly cavity; a stage of menstrual cycle. Women of genital age have ovulation periodically (each 21-35 days). Its periodicity is regulated by neurohumoral mechanisms, mainly gonadotrophic hormones of anterior lobe of hypophysis and a follicular ovary hormone. Accumulation of follicular liquid and thinning of overy tissue promotes ovulation. Constant for each woman ovulation rhythm undergoes changes within 3 months after abortion, within a year after delivery, and also after 40 years, when organism prepares for preclimacteric period. Ovulation stops with approach of pregnancy and after fading of menstrual function. Establishment of ovulation term is important at a choice of the most productive time for fertilisation, artificial insemination and extracorporal fertilisation.

Short-term pains in the bottom of a stomach can be subjective signs of ovulation, increase of mucous secretions from vagina and decrease of rectal temperature in a day of ovulation with its increase next day, increase progesterone content in plasma of blood, etc. - are objective sings. Ovulation infringement is caused by dysfunction of hypophysial-ovary system and can be caused by inflammation of genitals, dysfunction of adrenal glands or thyroid gland, system diseases, tumours of hypophysis and hypothalamus, stressful situations. Absence of ovulation at genital age is shown by menstruation infringement (1-2 days), menolipsis, disfunctional uterine bleedings. Anovulation is always at the bottom of a woman’s barreness. Restoration methods are defined by the reason that caused anovulation, and reference to a gynecologist and special treatment.

Some women experience peak of sexual excitability in ovulation days. However, use of a physiological method of contraception against pregnancy, based on sexual abstention during ovulation time, is especially difficult for young spouses, whose frequency of sexual acts reaches rather high level. Besides, at strong love excitements and nervous stresses additional ovulation can occur (especially at incidental, irregular intercourses) and then not one ovary ripens during menstruation, but two.. It is necessary to remember this, choosing this or that way of contraception.

Methods and ways of ovulation definition

Calendar method

Its essence is that menstruation always comes in 14 days after ovulation. That is if a cycle is 28 days — ovulation comes on 13-14th; 30-day — on 15-16th, etc. A problem is that modern city women have cycle failures too often. And even the healthiest ones have cases (1–3 times a year), when ovulation does not come at all, and menstruation comes its turn. In general, reliability of calendar method — no more than 30 %.

Tactile method

The given method approaches only to very observant women. It is noticed that the day before and during ovulation time, slime secreted from uterine neck, becomes less viscous — so that spermatozoa could move ahead on it easier. It is a very subjective method.

Basal temperature method

The given method is as reliable, as antierotic. If every morning, without getting up, you take temperature in a rectum (5–6 minutes) and compose a schedule, it is possible to find out that the straight line of temperatures falls in the day of ovulation! And returns next day. If one of cycles suddenly passes without ovulation, this also will be reflected in the schedule. Having traced thus 2–3 cycles, you learn to “catch” the necessary day to within 90

But, having imagined, how loved one bears me a thermometer (you cannot rise!), and I put this piece, I apologise - you know where, I absolutely ceased wanting to make love. Even for the sake of children!

Ovulation test

You can buy an ovulation test. There is no sense to resort to antiquated methods, when more authentic and less tiresome means are invented, allowing to define the best day for conception. The test is an indicator reacting to the raised maintenance of hormones (let’s name them «ovulation hormones») in a woman’s organism. Tests define ovulation approach on saliva and urine.

ULTRASONIC

On the 7th day of a cycle a doctor defines (with help of intravaginal gauges), whether an ovary ripens, where it is (this is important if, for example, there is a soldering, then conception can be planned, only when ovary grows ripe from an opposite side), when ovulation will take place. Theoretically this method allows planning even a sex of a child. It is supposed that girls are conceived a couple of days to ovulation, and boys - in a day of ovulation.
