There are many factors that cause anovulation and here are some common causes of anovulation.
Hypothalamus-pituitary-ovarian-axis dysfunction. This is caused by problems of hypothalamus or pituitary gland in the brain. As a result the hormones are not balanced which does not trigger ovulation and leads to infertility. The reasons that affect hormone balance include stress (see below); the other common causes are excessive exercises and/or underweight.
As we already known that subtle environmental changes may alter the menstrual cycle and cause anovulation. For example, summer camp menstrual disturbances and exam anovulation. Women in emotional stress could have no ovulation. This is temporary situation. If women get out of the stress environment, menstruation and ovulation could be returned. However if this situation is prolonged, anovulation could be persistent. Finding the causes of stress situation and avoiding the causes are the keys for ovulation to return. Many therapies could help reduce stress, such as psychological therapy, yoga and acupuncture etc.
Ovarian causes. If ovary does not respond to FSH and LH, this also causes ovulation problem.
Polycystic ovary syndrome (PCOS). This is commonest cause of anovulation related infertility. It explained 70% of the cases. Women with PCOS have imbalanced hormone levels. This may produce multiple cysts in ovaries, irregular period cycle, anovulation, infertility, acne and excessive hair growth and other symproms.
Premature ovarian failure (POF). In women with POF, their ovaries fail to function properly before menopause occurs. The ovaries don’t respond to FSH and there is no ovulation. They have difficulty to get pregnant.
Treatments that reduce stress can be effective to improve ovulation. Acupuncture helps treating anovulation by stimulating nerve endings and correcting hormonal imbalance. Acupuncture is very effective treatment for anovulation. Acupuncture reduces stress by regulating response to stress and altering stress related chemical substances levels; improves hypothalamus-pituitary-ovarian axis function and regulates blood hormone level. As a consequence, it improves ovulation and pregnancy rate.
Here are some clinical reports about the effectiveness of acupuncture on anovulation.
There was a control trial with acupuncture group and control group (treated with Clomephene). 25 cases in each group were given 6 cycles treatments. And then ovulation and pregnancy rate were compared between the two groups. Ovulation rate is not significantly different between the two groups. The pregnancy rate is higher (44%) in the acupuncture group than in the control group (16%).
There was a case report from a reproductive health institute center in Sichuan in China. They reported the effectiveness of acupuncture on women with anovulation. Ovulation rate was from 70-80% and pregnancy rate was from 40% - 60%.
Recently Yan and Liu summarised some case reports about effectiveness of acupuncture on increasing ovulation. They collected 21 papers which used acupuncture treated anovulation associated infertility.
Here are some typical cases.
Chen et al treated 42 patients with infertility associated with anovulation. 41 of them ovulated.
Kou et al used acupuncture treatment for 50 cases of anovulation associated infertility. 40 of 50 patients achieved pregnancy.
Chang et al used acupuncture for 32 patients with anovulation associated infertility. 9 patients achieved pregnancy during 1-3 month of acupuncture treatment. 22 patients achieved pregnancy over 4 months of acupuncture treatments.
Case report for effectiveness of acupuncture on infertility caused by anovulation
There was a study about effectiveness of acupuncture for infertility without ovulation. There were 50 women with infertility without ovulation. There women were divided into two groups: acupuncture group and control group. Control group was treated with clomiphere and injection of chorionic gonadotropin. The period of treatment was 6 cycles and ovulation rate and pregnancy rate were measured. The results showed that there was no difference in the ovulation rate between the acupuncture group and clomiphere group. However the pregnancy rate in acupuncture group was significantly higher (44%) than that for control group (16%). In addition the score of mucus and endometrial thickness was greater in acupuncture group.
This is a case report on effect of acupuncture treatment of infertility caused by ovulatory problems. 120 patients with infertility caused by ovulatory problems were divided into two groups: acupuncture group and clomiphene control group. 3 treatment cycles were applied. Result showed that similar ovulation rate was observed in both group, but pregnancy rate was higher and abortion rate was lower in acupuncture group compared to control group.
