Infertility is fundamentally the inability to conceive a baby, including the inability of a male to provide normal sperms and the state of a female who is unable to carry a pregnancy to full term [[1]]. The causes of infertility include specific male causes, specific female causes, combined and unexplained infertility (Fig. 2, [1]). On the male side, low semen count and quality due to endocrine problems, drugs, radiation, infection, hormone imbalance, and blockage of the man’s duct system are the common causes. On the female side, egg released not at the optimum time for fertilization, problems of releasing eggs, structural problems in the Fallopian tube, endometriosis, pelvic inflammatory disease, age-related factors, imbalanced hormones and uterine problems are the common causes of infertility. Genetic factors, DNA damages, diabetes mellitus, thyroid disorders, adrenal disease, hypothalamic-pituitary factors, environmental factors (such as toxins, physical and chemical agents and smoking) can cause infertility on either sex. In addition, approximately one in five couples will experience unexplained infertility despite completing a full infertility work-up. One in six couples in Australia and New Zealand suffers infertility [[2]]. Worldwide, 3-7% of all couples have an unresolved problem of infertility and 12-28% of all couples experience this problem for at least one year [1]. The infertility is highly related to the age. The older the age, the more problems on the fertility (Fig. 3, [[3]]).

 

Depending on the causes, infertility can be treated with psychological adjustment [[4]], medicine (Clomid, Pergonal, Follistim, Metformin, Parlodel, etc.) [[5]], surgery (Fallopian tube sterilization reversal, hydrosalpinx removal, testicular sperm aspiration, vasectomy reversal, etc.) [[6]], artificial insemination, or assisted reproductive technology (conception cap, semen collectors, intracervical and intrauterine inseminations, In-vitro fertilization and donor insemination, etc.) [1]. Many times these treatments are combined. One thing is very important for the infertility treatment: when starting the treatment to adjust the molecular metabolisms and functions, the organic diseases of infertility must be excluded.

 

There is a long recorded history of Traditional Chinese Medicine (TCM) being used in the treatment of infertility. In fact, records indicating herbal treatment of infertility and miscarriage date back to 200 A.D., including mention of formulas that are still used for those same purposes today [[7]]. Since the most situations of infertility are due to the imbalances of the molecular metabolisms and functions, while TCM has advantages at the regulations of functional balances individually, TCM shows many benefits in the treatment of infertility. TCM believes that women infertility is due to the lack of innate endowment, excessive intercourse, deficiency of kidney essence, deficiency of Chong and Ren channels; or deficiency of kidney yin, deficiency and cold of the uterus; or body weak, deficiency of Yin and blood, lack of nourishing womb and pulse; or sluggish emotion, stagnation of liver Qi, dissonance of Qi and blood; or obesity, excessive eating and rich fatty diet, Yang deficiency of spleen and kidney, the development of phlegm dampness, block of Qi, block of Chong and Ren channels; or blood stasis and condensation, accumulation of diseases in womb [[8]].

For male infertility, TCM believes that kidney stores essence and control reproduction; It is the material basis of human growth, development and reproduction. The imbalance of kidney Yin and Yang, especially the kidney deficiency, is one of the main pathological mechanisms of sterility. The other mechanisms include deficiency of Qi and blood, Qi stagnation and blood stasis, damp heat of essence room, liver depression and blood stasis, and so on. The followings are the common types of infertility and treatment for women in the clinics [[9]]:

Note: Chapter 21 of the Jin Gui Yao Lue (Essential prescriptions of the Golden Cabinet – 金 匱要略) is dedicated to Women’s Miscellaneous Disease and one particular formula Wen Jing Tang (温经汤) stands out: Line 22.9: … [this formula] also governs women’s lesser abdominal cold and chronic failure to conceive; it also helps to eliminate blood from flooding or excessive menstrual bleeding or failure of the menses to arrive [at their proper] time.

 

Fertility is a complicated procedure of sperms and ova reactions, including spermatogenesis and oogenesis, transportation of gametes, fertilization and fetal development in the precisely regulated molecular environments through the whole procedure. Any imbalance of these molecules may lead to the infertility [[10], [11]]. The recent medical sciences demonstrate that TCM formulas regulate the body molecular balances and lead to the recovery of diseases [[12], [13]]. One study showed that the management of female infertility with Chinese Herbal Medicine can improve pregnancy rates 2-fold within a 4 month period compared with Western Medical fertility drug therapy or IVF [[14]]. In addition to the treatments of infertility with western medicine, TCM plays a very important role in helping many many couples to realize their dreams to have a baby.
