Dr Lewis presents a holistic and well researched book that may bring hope to infertile couples that western medicine has given up on. Drawing on the Chinese Traditional Medicine paradigm she shows sensible (and correctable) reasons why women may not get pregnant - even though western medicine can find no reason. She gives details of treatments available for a multitude of conditions affecting fertility, from endometriosis, through PCOS and advanced maternal age, and sperm count problems and even including physical damage to fallopian tubes. She has helped many couples to have the babies they longed for and brought them better health along the way. A friend of mine had been trying to get pregnant for 2 years and after doing the questionnaires in the book discovered that her very short period may be to blame. Dr Lewis suggests any woman having a period shorter then 3 days will find it difficult to get pregnant. My friends gynaecologist said a 36 hour period was perfectly normal. She is now following the recommendations in the book herself as she has no access to a Chinese Doctor as she's not in the UK. Please, if you are trying to get pregnant and are having problems, investigate this book - it could be the answer to your problems.
