Ovulation disorder is a condition caused by many causes, resulting in the phenomenon of ovum not being released according to a certain cycle, irregular shedding, thereby causing menstrual disorders. female infertility. This is a very dangerous disease, greatly affecting the fertility of women if not detected early and treated definitively.
Normally, every month, a woman's ovaries have a follicle that grows to a certain size, then ovulation occurs (ovulation). When the ovaries are ovulating regularly, the hormones secreted by the ovaries will cause uterine bleeding to occur according to the menstrual cycle. This ovulatory disorder often leads to missed periods, irregular periods, or prolonged periods. Therefore, ovulation disorder is the main cause of infertility.
Ovulation disorder is a very common disease. This is because the ovarian cycle is so complex that even a small change can disrupt the cycle and interfere with ovulation. In most cases of delayed pregnancy due to an ovulatory disorder, the main cause is a hormonal imbalance, ie the body does not produce enough hormones or at the wrong time. Excessive weight gain or weight loss can also affect ovulation.
Ovulation disorders have no specific symptoms and are usually detected through oocyte ultrasound. However, the case of ovulatory disorder often has some obvious symptoms such as: menstrual irregularity, not having a period for a long time, abnormal changes in uterine mucus, and decreased libido. sex, obesity, hirsutism...
When we detect any of the above abnormalities, we should go to a specialist for timely treatment. Only when the cause of ovulation disorder is clearly identified can the most effective treatment be instituted.

Because, during a menstrual cycle, a woman's body needs to produce enough estrogen to build the lining of the uterus. Excessive weight loss and reduced caloric intake can affect the hypothalamus, an organ responsible for regulating various processes in the body including the menstrual cycle. As a result, the body will not be able to produce enough estrogen needed for menstruation. This is the main cause of missed periods.

Patients with amenorrhea are mostly marathon runners, ballet dancers, bodybuilders and other professional athletes. In short, if you're exercising "too hard" and aren't consuming enough calories, your body won't be able to produce enough estrogen to maintain a normal menstrual cycle. To fix it, you need to slow down a little, eat a little more and exercise a little less. This will help get our body back on track.

The hypothalamus, which is involved in the production of the hormone estrogen during menstruation, is greatly influenced by hormones caused by stress, such as adrenaline and cortisol. Stress due to family, work pressure or anything that makes us stressed are all causes of menstrual disorders.

Not only that, long-term smoking also causes problems with the fallopian tubes, reduces the quality and quantity of eggs and leads to infertility.

Normally, a woman's perimenopause period falls around the age of 42. This is when the body begins to produce less estrogen, which affects the menstrual cycle.
