Part A: INTRODUCTION INTRODUCTION According to the World Health Organization, the percentage of infertility couples accounts for 12-18%, varying in countries, an average of 15% Sperm decline has been increasing and occupying a high proportion According to WHO studies, the minimum sperm density decreased from 40 million/ml (1980) to 20 million/ml (1999), and 15 million/ml (2010) The progressive sperms declined from 50% (1999) to 32% (2010) The treatment of sperm decline still faces many difficulties, mainly because sperm decline has many complicated causes Modern medicine has many methods of treating sperm decline, but the results are lower than the expectations of physicians and patients, due to unwanted effects and long time treatment which have great effects on patients’ health and economy Balanophora sp of Balanophora genus, three species of Balanophora fungosa indica, Balanophora latisepala, Balanophora laxiflora have been found in Tuyen Quang, Hoa Binh, Lao Cai and Yen Bai provinces Balanophora sp is often decocted or soaked in wine to support the treatment of male diseases as impotence, unconscious semen leakage, nocturnal emission infertility, and has shown very good results The pharmacological effects of Balanophora sp has currently been being researched on the treatment of reproductive malediseases Balanoxi hard capsules are formulated from total dry extract of Balanophora indica OBJECTIVES OF THE RESEARCH Studying the acute and semi-chronic toxicity of Balanoxi on the experimental animals; Assessing the effect of Balanoxi on sperm decline caused models; Research the effect of Balanoxi on infertility patients due to sperm decline PRACTICAL MEANING AND NEW CONTRIBUTIONS OF THE RESEARCH The dissertation is a scientific work conducted systematically from experimental to clinical levels on Balanophora indica, a valuable Vietnamese medicinal herb that has long been used in the folk Research results showed that Balanoxi has no oral toxicity, has protective effects, recovers reproduction, increases serum testosterone, increases the quantity and quality of sperm The results of the study can be applied on male fertility treatment,its contributions are, therefore, very practical THE STRUCTURE OF THE DISSERTATION In addition to the introduction and conclusion, the dissertation has chapters: Chapter 1: Overview 36 pages Chapter 2: Materials, subjects, and research methods 16 pages Chapter 3: Research results 45 pages Chapter 4: Discussion 36 pages The dissertation has 54 tables, 13 charts, pictures, 19 appendices, and 118 references (44 in Vietnamese, 71 in English, and in Chinese) Part B: CONTENT CHAPTER 1: OVERVIEW 1.1 VIEWS OF MODERN MEDICINE ON SPERMS, SPERM DECLINE, AND TREATMENT OF SPERM DECLINE 1.1.1 The causes of sperm decline - Sperm decline due to Gonadotropin Releasing Hormone (GnRH) disorders: Certain reproductive hormones play a crucial role in sperm production and development in general as well as in the differentiation stages of sperm development Pathological disorders of reproductive hormones lead to a huge change in the number and quality of sperm: + GnRH deficiency + Excessive endocrine excretion - Sperm decline due to disorders of sperm production in the testicles + Sperm decline due to genetic diseases + Sperm decline due to testicular damages + Sperm decline due to a number of other causes + Sperm decline due to diet, bacterial infections, high temperatures, immune factors, living conditions, X-rays, illness, stress, etc 1.1.2 The methods of sperm decline treatment of modern medicine As the causes of sperm decline are complicated and they often coexist together, it is necessary for physicians to prescribe reasonable treatment such as a combination of medical, surgical, and fertility treatments to increase the rate of pregnancy - By medication: medication treatment should be indicated for patients with sperm decline due to unknown etiology.Commonly used medications: Antioxidants (Glutathion, L-arginin), hormones (Gonadotropin, Androgen, and estrogen receptor antagonists) - Surgery: surgery should be indicated for patients with impaired spermatozoa that affect the sex life, such as varicose veins, ectopic testicles, testicular water or inguinal hernia Connective surgery should be indicated for patients with no sperms by connecting vas deferens The main assisted reproductive technologies for treating male infertility due to sperm decline include IUI, IVF, and ICSI 1.2 VIEWPOINTS OF TRADITIONAL MEDICINE ON SPERMS, SPERM DECLINE, AND TREATMENT OF SPERM DECLINE 1.2.1 Conceptions of traditional medicine on the process of Jing production and the factors affecting the Jing production - Jing, according to traditional medicine consists of two types (inborn Jing and after-born Jing), it is the basic material for body composition and body nutrition During body development, Jing is always consumed and also regularly replenished by spleens to maintain living activities Both types of Jing are stored in the kidneys 1.2.2 Disease types and the treatment of sperm decline according to traditional medicine * Jin Kidney deficiency type: darkish face, dizziness, ringing in the ears, weak and tired back and knees, loose or falling teeth, growing gray, tiredness, forgetfulness, impaired memory, dullness, weak limbs, slow movements, rapid aging, impotence, no conception, low semen volume, sperm deficiency Taut deep no force Chi pulse, if there is Yin deficiency Fire excess, there will be five center restlessness and fever, reddish tongue, less moss, taut pulse Strategies: Reinforcing Qi and Nourishing and Tonifying Yin Kidney Remedies: ‘Zuogui wan’ and ‘Wuziyanzong wan he liuwei wan’ * Yang Kidney deficiency type: darkish face, fear of cold, cold feet, back and knees are tired and cold; Patients feel tired, uninterested; large amount of urine, urinating many times, loose stools in the early morning; Low sperm count, weak sperm motility, impotence, premature ejaculation, deep fine pulse or deep slow pulse, pale tongue, white moss Strategies: Warming Kidney and enhancing Yang, tonifying Jing and reinforcing Qi Remedies: ‘Jin guishen Qi wan’, ‘wuziyanzong’, and ‘Yougui Yin’ * Spleen deficiency Jing damage type: fatigue, pale face, dizziness, headache, forgetfulness, poor appetite, bloating, low sperm count, sperm vitality weakness, impotence, premature ejaculation, tongue quality, rough, white tongue moss, forceless pulse Strategies: reinforcing Qi and invigorating Spleens, nourishing blood and promoting the production of Jing Remedies: ‘Gui pi tang’ (sheng fang ji) and ‘bazhen sheng jing tang’ *Liver Qi stagnation and Qi stagnation blood stasis type: weak sperm, high death rate, low sperm count, painful testicles, testicular vein, impotence, feeling of bloating in chest and stomach, darkish tongue with blood stasis spots, sluggish taut pulse or rapid taut pulse Strategies: dispersing the stagnated liver Qi; alleviating mental depression, nourishing spleens and regulating nutrients from food; promoting blood circulation, removing blood stasis and restoring Jing flow Remedies: ‘Heijiaoyao san’ (he jiju fang) and ‘xuefuzhuyu tang’ (yi Lin gaituo) * Wetness heat in lower jiao type infertility: backache, tired legs, fatigue, feeling bitter in mouth, anorexia, dizziness, dry mouth without wanting to drink water; itching or severe genital irritation, soreness and obstruction in perineum or testes, dense semen with foul odor, which can be inferred semen contains many red and white blood cells; low sperm count, high dead sperm rate, cloudy urine, burning sensation in the urethra during urination or ejaculation; reddish tongue, yellowish moss, rapid smooth pulse or soft smooth pulse.Strategies:Clearing heat, promoting diuresis to eliminate wetness evil, and removing toxic substances Remedies: ‘Pi jie fen Qing Yin’ (dan xi xinfa) and ‘Long tan zuogan’ (yi sun jinjian) 1.2.3 Overview of Balanophora sp There are about 20 species of Balanophora sp in the Balanophora genus In Vietnam, only three species of Balanophora sp have been found namely Balanophora fungosa indica, Balanophora latisepala, and Balanophora laxiflora Balanophora indica is found in moist or broadleaf limestone forests Its samples were collected in December 2015 at the summit of Hong Mountain in Khuon Man, Binh Yen, Son Duong, Tuyen Quang The scientific name is assessed at the Vietnam Institute of Medicinal Materials In Vietnam this medicinal plant is often used as a tonic for postpartum women to stimulate appetite In particular, this medicinal plant is often soaked in winefor men to enhance and endure erections In Malaysia, all Tinosporacapillpes Gagep is also used as aphrodisiac Effects according to traditional medicine - Pharmacological properties: Sweettaste has the effects of warming channels, liver, kidneys, and colon Balanophora sp has two main therapeutic effects: notifying kidneys and supporting kidneys, which are suitable for treating impotence, infertility, tired legs, and exhaustion; and laxative, suitable for treating fluid deficiency disorders which lead to dry intestines, and constipation - Mainly treating physiological weakness, impotence, frigidity, backache, knee pain, and anorexia CHAPTER 2: MATERIALS, SUBJECTS, AND RESEARCH METHODS 2.1 MATERIALS FOR RESEARCH Balanophora indica samples were collected in December 2015 at the summit of Hong Mountain in Khuon Man, Binh Yen, Son Duong, Tuyen Quang The scientific name is assessed at Vietnam Institute of Medicinal Materials Balanophora indica is produced at the Research and Application Center, the Military Institute of Traditional Medicine, under its standards 2.2 RESEARCH SUBJECTS The white mouse, Swiss strain, both sexes, weighing 18-22 grams, used to study acute toxicity and the effect of the medication on fertility and on chromosomes Newzealand White rabbits (semi-chronic toxicity test), white fur, healthy, both sexes, weighing 1.8 -2.5kg;
