Initial consultation The patient, Ms. Liu, visited the clinic on January 25, 2015 because she had planned to get pregnant for six months but was not pregnant. The patient had a full-term normal delivery on March 18, 2012 and resumed menstruation one year after delivery, with a usual menstrual cycle of 28-30 days, which cleared in 6-7 days, and her last menstruation on January 19, 2015. In the past six months, her menstrual cycle was shortened to 23-25 days, but the cycle was still regular and the menstrual volume decreased. She had taken oral motherwort capsules to regulate her menstruation, but her clinical symptoms did not improve significantly. The patient usually uses safe period contraception and started to plan pregnancy half a year ago. The semen of her spouse was normal, but she has not yet conceived, so she came to our hospital for consultation. After general examination, the patient was found to have a body temperature of 36℃, heart rate of 82 beats/min, respiration of 18 breaths/min, blood pressure of 112/60mmHg, normal development in appearance, good general condition, no abnormalities in cardiopulmonary auscultation, flat and soft whole abdomen without palpable mass. Gynecological examination showed normal vulvar development, even distribution of pubic hair, vagina was married menstrual style with a small amount of menstrual blood in the vagina, uterus was horizontally positioned, normal size, normal activity, no pressure pain, and no abnormalities were palpated in the bilateral adnexal areas. Other ancillary examinations suggested that the anti-müllerian hormone was 0.25ng/mI. Ultrasound examination showed no abnormalities in the uterine adnexa, and the patient was initially diagnosed as having decreased ovarian reserve function. First of all, the patient’s diet should be regulated, such as eating more fresh fruits and vegetables, more fish and eggs, more milk, especially vitamin-rich foods and foods rich in unsaturated fatty acids. Patients should also develop good living habits, do not stay up late, enhance their physical fitness, keep their mood relaxed, and let them have more entertainment, watch more positive TV and books, etc. Secondly, after examination, the patient did not have estrogen-dependent diseases and thrombotic tendency, so she was given oral estradiol valerate tablets and progesterone soft capsules for 7 months for hormone supplementation, as well as traditional Chinese medicine, such as oral Zhi Kidney Fertility Pill. After 7 months of treatment, the patient’s menstrual flow returned to normal and her menstrual cycle returned to 25-28 days. The auxiliary examination showed that the anti-Müllerian hormone was 2ng/ml. After 12 months of treatment, the patient had a blood test on January 5, 2016 due to 40 days of menopause and was found to have 3000 mIU/ml of human chorionic gonadotropin, and an ultrasound examination was performed on January 10, 2016, which revealed a 2 cm intrauterine gestational sac and germ tissue, indicating a successful pregnancy. IV. Precautions We are glad that the patient is in remission and successfully conceived after treatment. The patient is advised to continue her maternity checkups and establish a maternity health card, and to abstain from sexual intercourse during the first 3 months of pregnancy and the last 3 months of pregnancy. It is also important to take rest and exercise properly. It is recommended to take a walk every day in order to promote gastrointestinal motility and appetite, but no strenuous exercise or heavy physical labor. In general, we should eat more fresh fruits and vegetables containing vitamin C, more protein and a reasonable nutritional mix. Avoid contact with toxic and harmful gases and objects, avoid second-hand smoke, and it is recommended to attend weekly health classes for pregnant women, so as to prepare for eugenics. V. Personal insight Decreased ovarian reserve function is usually easy to be ignored, so when patients have decreased menstrual flow, they do not check their ovarian reserve function in time, but come to the clinic only when oral Chinese medicine is not effective. Although the results are good after treatment, other women should seek medical attention as soon as clinical changes in menstruation or infertility are detected, so that the cause can be detected and treated according to the cause as early as possible, in order to make the symptoms improve to achieve pregnancy.
