Two of ovulation in one cycle: can be 2 times, at different times of the month

Sometimes, the light appears not ordinary twins - and even unlike heterosexual. This is made possible thanks to an unusual phenomenon when a woman's body was 2 ovulation per cycle. In this case, a pregnant bear children, developing from different eggs fertilized by different sperm.

Double ovulation - not an uncommon phenomenon. According to statistics, with her face every 10th woman. This phenomenon is not fully understood, however, physicians have identified a number of factors that increase the probability of ovulation in one of two loop.

Determination of ovulation

Menstrual cycle - is a monthly training of the female body to conceive a child. Under the influence of hormones occur the following processes:

• in the ovary matures and prepares for a fertilized egg;
• endometrium in the uterus is formed for fixing and embryo supply;
• there are changes in the mammary glands.

On Ultrasound at the time of ovulation you can see the dominant follicle - its dimensions are close to 20 millimeters. Around the middle of the cycle, for 12-14 minutes a day, ripened egg is released from the follicle, leaving the ovary and begins to move into the uterus the fallopian tube. This process is called ovulation. Its duration is 1-2 days, conception can occur only in the ovulation period.

Normally, in a woman's body every month one egg matures. After completion period favorable for conception, progesterone levels begin to rise suppressing follicle maturation.

However, under the influence of a number of factors egg output can occur several times a month. The interval between them is from several hours to several days. This phenomenon is called "double ovulation." Very rare maturing in one cycle of three or more germ cells.

When ovulation occurs again

The probability of a double ovulation per cycle - one of the reasons for the need for contraception, not only 2 days per month. Maturation second female reproductive cells in the same menstrual cycle differently can occur. Classify process variations can be on the following parameters:

• cells from mature follicles and out simultaneously or at intervals of from several hours up to 7 days;
• they are formed in one ovary or two different.

The fact that this process can occur twice per cycle, it often happens confirmed birth dizygotic (DZ) twins. If children of different sexes, it can be stated with certainty that the mother was the maturation of the egg twice a month.

Multiple pregnancy is possible in the case of a single ovulation, but if kids have a completely identical genetic code. They strictly gay and very similar to each other.

Causes and symptoms

Maturation two follicles per cycle - not quite a common phenomenon. Presumably, it is due to the influence of factors such as:

1. Genetic predisposition. The birth of dizygotic twins may be characteristic for several generations of the same family.
2. Severe stress, nervous stress, rape. Emotional shocks provoked release of luteinizing hormone responsible for the maturation of follicles.
3. Irregular, occasional sex.
4. Application inwardly grasses (infusions, tinctures) containing phytoestrogens.
5. Cancel hormonal contraceptives.
6. Age older than 35 years.
7. Medication support IVF procedure. Used drugs stimulate the activity of the gonads, that may lead to the deviation in the cycle.

The causes of the phenomenon are not fully understood. However, the above factors with high probability may start the process of the second follicle growth in a cycle.

External signs of double ovulation conditional and may go unnoticed. Usually these symptoms point to this process:

• increased libido;
• discomfort in the area of ​​one or both ovaries;
• engorgement, breast tenderness;
• changes in taste;
• pulling and aching pain in the lower abdomen;
• Reinforced flatulence;
• increasing the number of cervical mucus secretion;
• increase in basal body temperature.

When these symptoms are repeated twice in the cycle (with a break), there is reason to guard. Perhaps these are signs of a second ovulation.

Some women say they can feel the release of the egg process. For the rest, the only reliable way home diagnostic test remains.

The time lag between the oestrus cycle

All cases of this phenomenon can be divided into two main types:

1. Double ovulation when the egg comes out at the same time or with a difference of a few hours (under the influence of a hormonal waves).
2. Repeated ovulation in one cycle. Wherein a difference of a few days there is a second level rise gonadotropic hormones, follicle growth of the second precipitating. The time lag in this case is from 1 to 7 days.

One week after the first egg output ends forming the corpus luteum. When this concentration reaches a level of progesterone, excluding the possibility of re-ovulation.

Double ovulation and menstruation

Double ovulation can sometimes affect the usual course of the cycle, but it does not always happen. If the egg follicles are left at the same time or with a minimum time interval, and the conception has not occurred, menstruation takes place as usual. It comes in time and lasts on time.

If ovulation occurred at different times, you can change the usual cycle scheme. There are cases when menstruation began as usual, it came to an end, and a few days later repeated. In situations where a single cycle matured two eggs, this development is sometimes possible. But it is rather an exception to the rule.

Conception and pregnancy

In the presence of factors possessing many women may be two of ovulation in one cycle. However, pregnancy is caused not only by them, so the dual conception does not occur in every case.

Double ovulation, subject to the successful fertilization of two eggs, can cause the birth of twins. Children can differ markedly in appearance and be heterosexual, because the conception took different sperm involved.

Phenomenon when the body ripen several eggs, more common in women blacks, at least - at the European women, is extremely rare - in Asian women. This is partly genetically determined indicates this deviation.

Simultaneous maturation of two or more follicles leads to the fact that during the same menstrual cycle in women twice it is possible to conceive a child. The time gap between these periods may cause a very rare phenomenon - a multiple pregnancy different from men. That is the first egg is fertilized by the sperm of one man, and the second - the other. In medical practice, formally recorded about 11 such cases.

Reliable diagnostic methods

Maturation of two or more follicles can be triggered by various factors during one cycle. For example, such an effect may lead to stimulate ovarian appropriate medication in the treatment of infertility.

Not all women are able to feel the rupture of the follicle, so there are special methods to determine a double ovulation.

1. At home, help regular ovulation test (Available at pharmacies). If he gave a positive result with a difference of a few days, it indicates the maturation and release of the second egg.
2. In the clinical setting is a rare phenomenon can be seen with ultrasound. The most informative study will be at the end of the cycle. accuracy of the result depends on the doctor's professionalism and class of device.

From time to time, many women have two ovulation in one cycle. However, this phenomenon should not be permanent. If this occurs often or regularly, it is a reason to see a doctor to correct the condition. Specialist order tests to help identify the reasons for rejection.
