Many women equate decreased menstrual flow with diminished ovarian function, which is actually a misconception. So, what are the symptoms that would indicate that your ovarian function is starting to go downhill? This is something that many women who have a desire to have a second child would like to know. In terms of menstruation, it is the shortening of the menstrual cycle, the menstrual period and the decrease in the volume of menstruation. If your menstrual cycle was originally 30 days but has become 25 or 26 days, and your menstrual period was one week but has become three or four days, you should check your ovarian function. How to check ovarian function During your menstrual period, that is, on the 2nd to 4th day of your period, you should have your blood drawn for an endocrine check. You can also have a blood test for AMH (a hormone that measures ovarian function) and a menstrual ultrasound. You can also have a menstrual ultrasound, which is done mainly to see the number of small follicles. This is the time when the small follicles are not developed and the number of small follicles can be seen more clearly. If you wait until ovulation, there will be one grown follicle and other small follicles will not be visible, and the number of small follicles is an important indicator of ovarian function. There are four treatments to try if the ovarian reserve function is declining Can ovarian function be improved if the ovaries are declining? This is probably the most important concern for women who want to have a second child. There are several methods commonly used, but each person has a different degree of decay and no one method can ensure that the ovaries will be rejuvenated. 1. Use DHEA, which also goes by the name ‘youthin’, a substance extracted from yam that has a weak androgenic function that promotes adrenal hormone secretion and improves egg quality. This method is used in about one third of reproductive medicine centers around the world, and is the more common way used today. 2. Use vitamin D. 3. Use coenzyme Q10, an antioxidant substance that slows down the aging of mitochondria and improves egg quality. Both the second method and the third method can be used as auxiliary methods along with the first one. 4. The use of growth hormone can also improve egg quality, but older women should be cautious with growth hormone as it may increase the risk of tumors, so younger women use more of it. These four methods can be tried one by one, usually with three months, the effect can be tested, if the ovarian function has not been improved, it means that these methods are not effective for the patient, and other artificial assisted reproduction techniques can be considered.
