Do you want to get pregnant efficiently? Men can produce thousands of sperm per day, while women only produce one egg per month, so it is crucial to catch a woman’s ovulation period. Here we will teach you a few tricks to determine the ovulation period, so you can improve the efficiency of pregnancy! 1. Menstrual Cycle – Luteal Phase A woman’s normal menstrual cycle is 21-35 days, with an average of 28 days. If your menstrual cycle has been around 28 days a very stable time, then congratulations, you have normal ovulation about 10 times a year or more. For you who have regular periods, the life span of the menstrual corpus luteum after ovulation is 12-16 days, which we consider an average of 14 days. For every woman, the length of the luteal phase is the same, so ovulation is the menstrual cycle minus 14 days. As an example, a woman has a regular menstrual cycle of 30 days, so her ovulation period is about the 16th day of her menstrual cycle, i.e. 30-14=16 days. However, if you have irregular periods, this method will not be applicable. 2. Body temperature measurement In addition to relying on a regular menstrual cycle, scholars have found that progesterone in the body after ovulation raises a woman’s body temperature slightly, slightly referring to about 0.5℃. The first thing you do when you wake up every day is to take your body temperature with a mouth meter in your mouth and record it from the first day of your period to the first day of your next period; connect them into a line, the body temperature after ovulation will be 0.5℃ higher than before and last until the next menstrual period, then the overall trend of the post-ovulatory curve is also higher than that of the ovulation period. This method is relatively delayed and retrospective, and by the time the temperature is found to have risen, the egg has already been expelled. The temperature measurement method is also not very accurate, as there are many factors that influence it, and the temperature changes around ovulation are not particularly pronounced. This method can be considered at your discretion. 3, changes in the leucorrhea In addition, careful you may have noticed that there are a few days in the middle of the menstruation leucorrhea is more, colorless and transparent, the degree of drawing is very good, this is also the performance of the ovulation period. Because of the maturation of the follicles, the estrogen in the body rises, the secretion of the glandular cells of the uterus increases, so the vaginal secretions will undergo the above-mentioned changes. This is also a good time to conceive. 4, urine LH test paper In recent years, there are various urine LH test paper available in the market. Patients follow the instructions to test urine LH continuously every day from the time of menstruation and have intercourse if they find a strong positive result. The principle is that the hormone serum LH will rise sharply in the body before ovulation, so the LH in the urine will also rise, which can be measured by the test paper. However, this method is not absolutely useful; for some patients with a long follicular phase, it may not be possible to measure the peak; and for polycystic patients whose basal LH is already high, the test paper may always be positive. 5. Transvaginal ultrasound follicle monitoring The most reliable is transvaginal ultrasound follicle monitoring, which is suitable for all women with fertility requirements. Through ultrasound, we can visualize the number and size of follicles. Follicle monitoring is an intermittent and continuous process. The follicular phase of the menstrual cycle is the stage of egg growth and development until ovulation. Transvaginal ultrasound monitoring is to observe the follicles at this stage, so it is necessary to come to the clinic every other day, 4-5 times a menstrual cycle. Patients with relatively regular periods can have their first visit on day 8-12 of their menstrual cycle. After each follicle monitoring, depending on the lining and follicle size, we will tell you the time of your next follow-up visit, and if the lining is lagging behind the follicle growth, we will also add the endometrial growth estrogen in time. You may be wondering, how long does each monitoring session take? It only takes a few minutes to do a follicle monitoring. Lying on an examination bed next to the ultrasound machine, we find the uterus and ovaries by controlling the ultrasound probe and measure the endometrium and follicle size. If abnormalities in the endometrium and abnormalities in the ovaries are found they will also be documented in time to give you an account of your condition and some treatment recommendations will also be given. When the follicles are mature and the urine LH is strongly positive, we will instruct you to have intercourse. After intercourse, a monitoring will be done to confirm that the previously seen mature follicles have been eliminated to ensure the effectiveness of intercourse in this cycle. In rare cases, patients may return for monitoring after intercourse and find that the follicles do not break. We will give hCG injections, commonly known as egg breakers, at the next monitoring cycle to promote the final maturation of the follicles and ovulation. If the follicles do not break even after more than two breakage injections, this is a disease that needs to be treated by IVF fine needle aspiration for egg retrieval. If you ovulate successfully and do not have a period two weeks after intercourse, you can check to see if you are pregnant. If you have been treated with ovulation promotion, you will be advised to take oral progesterone to increase luteal support in order to ensure a smooth embryo implantation. Thus, it seems that transvaginal ultrasound follicle monitoring is a very accurate and effective diagnostic and therapeutic tool. Finally, there are a few more little secrets to tell you. In order to ensure the effectiveness of the monitoring, the male partner needs to have his semen routine checked first. Ovulation monitoring should only be done if the semen routine is normal; otherwise, even if the follicles are growing and maturing well, the sperm is too poor to combine with the eggs and it is impossible to get pregnant. If you have monitored your menstrual cycle for 6 consecutive cycles and found that the follicles are growing and discharging without problems and the sperm are normal, you should fully consider if there is a problem with the fallopian tubes. A tubal imaging should be done as soon as possible to clarify the diagnosis before deciding on the next step of treatment. For patients with ovulation promotion, if repeated ovulation failure occurs, IVF with high purity drugs for ovulation promotion is considered.
