Fertility and Nutrition: A review of data
The reproductive system
• The body is not a set of disparate organs
• The reproductive system is dependent upon the digestive and immune systems to maintain nutrient supply and health
Infertility
• In the USA 15-20 per cent of couples or 1:5 have fertility problems
• 65 per cent of these are helped by drugs and surgery to achieve a pregnancy
• Ballweg ML, Overcoming endometriosis NY p76
Fertility• In the UK 750,000 babies are born each year• 1:5 couples are sub-fertile• 40,000 babies are early and of low birth weight• 1:150 babies are lost through stillbirth• 1:4 pregnancies end in miscarriage
IVF• At present the success rate is only 10-30 per cent success
rate or
• 70 -90 per cent failure rate!!
Female sub-fertility
• Blocked fallopian tubes• Chlamydia/pelvic inflammatory disease• Hypothyroidism• Endometriosis• Amenorrhoea• Anovulation• Polycycstic ovaries• High pesticide or heavy metals
Chlamydia
• Chlamydia trachomatis
• Sexually transmitted pathogen
• More antibodies are found in infertile couples as opposed to fertile ones
• 50 per cent of infants born to chlamydia positive women develop infections
PolyCystic Ovary Syndrome
• Multiple follicles on ovary• Six or more immature ova• Hyperinsulinism• System loaded with insulin• Ovary produces testosterone instead of
oestrogen• Low chromium and zinc• Sugar/carbohydrate craving
Polycystic ovaries
• Hirsuitism
• Erratic menstrual cycle
• Acne
• Weight gain - thighs, hips, stomach
• Male pattern baldness
• Skin tags, nigra
Endometriosis
• Normal endometrium tissue begins to grow in the wrong place outside the womb
• Bleeding occurs within the peritoneal cavity giving rise to pain on intercourse, pain at menstruation and ovulation
• Ovarian ‘chocolate’ cysts may form
Symptomatology of EndometriosisDysmenorrhoea and/or pain throughout menstrual cycle
95%
Fatigue 87%Diarrhea, etc w/menstruation 83%
Abdominal bloating 84%Heavy/irregular bleeding 65%Dyspareunia 64%Nausea, etc w/menstruation 64%Dizziness/headaches w/menses 63%Low resistance to infection 43%
Infertility 41%Low-grade fever 32%
From 4,000 case histories from the Endometriosis Association Research Registry - compiled 1998
Women with Endometriosis are more likely to have:
• Auto-immune disorders - lupus, RA, MS
• CFS - 100 times more likely
• Fibromyalgia - twice as likely
• Hypothyroidism - seven times more likely
• Asthma, eczema, and allergies (atopic)
– Sinaii M et al, 2002, Human Reproduction, 17, 10, 2715-24
Male infertility
• Undescended testicles• Poor sperm quality• Low sperm count• Testicular cancer• Inaequate thyroid function• Impotence• Prostate problems• Genito-urinary infections• Malabsorption
Sperm
• 60 per cent of miscarriages are due to defective sperm
• 1: 20 men are subfertile
• Spermatogenisis in the human takes 120 days to recover if mutagens are around
– Skakkebaek N, KeildingN, Changes in semen and testes. BMJ 309:1316-17, 1994
Pregnancy outcomes
IDEAL - • Live birth - healthy & vigorous baby
ADVERSE -• Infertile• Miscarriage• Stillbirth• Perinatal death\sick baby
Terminology• infertility -no pregnancy after 12 months
unprotected intercourse• preterm - less than 38 weeks• low birth weight - less than 2500gm• congenital malformation
– 18 per 1000 births– foetal alcohol syndrome– infection syndrome - rubella– iatrogenic disaster - thalidomide
Ovaries
• All the eggs a woman will ever make are created in the foetal stage of her own development
• The egg that produces the grand-daughter was created by the grandmother
• New research suggests that women may be able to produce eggs throughout life

Preconceptual care
• Assessment of the health and well-being of prospective parents to allow this to be optimised for conception
Who needs preconceptual care?
•First time parents•Couples with fertility problems•Couples with previous poor pregnancy outcomes•Everyone?
The aims of preconceptual care
• to conceive
• to have an uncomplicated pregnancy
• to have a normal delivery
• to breast feed
• to adjust to a new baby
• to give children the healthiest start in life
Fertility assessment
• Genetic and family history
• Medical conditions
• Occupational risks
• Lifestyle - exercise, nutrition, toxin exposure, stress
Requirements for conception
• normal menstrual cycle & ovulation
• healthy sperm in sufficient numbers
• healthy reproductive organs
• normal sexual function
• timing
Importance preconceptual care
• Healthy gametes
• Before attachment to the placenta nutrients must be high in the endometrium
• Rapid embryonic growth rate
• Foetus almost fully formed by 8 weeks

Fertility• There is an endocrinal mechanism by which the females of
all mammalian species become infertile if food supplies are inadequate
• Down on the farm, in animal husbandry, it is well known that animals conceive on a rising body weight, not when weight is falling. All animals have a fertility threshold and in farming there still exists the practice of ‘flushing’. “The practice of giving ewes which are in fairly poor condition an improved diet for a few weeks before mating so that they are in a rapidly rising condition when they meet the ram. Flushing is not fattening up, it means supplying all the essential nutrients to make the hypothalamus and pituitary gland (and ovaries) provide an excellent hormone profile”.
– Coop IE. ‘Effect of flushing on reproductive performance of ewes’. 1966. J Agri Sci (Camb): 67:305-323
Poor Nutrition• Research into restricted calorie intake has been done at the
University of Pittsburgh, and it was discovered that ‘fasting for one day alone can change the suppression of luteininzing hormone (LH)
• The implication for slimmers is that even short-term deficiency can have a profound effect on endocrine function
• Other studies offer similar conclusions, suggesting that ‘restrained eating may be a marker for metabolic and emotional disturbances, and may also be associated with biological suppressed, no message would be sent.
• Women with abnormal menstrual cycles experienced ovulatory disturbances including low progesterone and short luteal cycles
• If you are restricting nutrient intake in order to lose weight, you may be damaging your chances of becoming pregnant
Fertility• Inability to ovulate is clinically called ‘luteinized
unruptured follicle syndrome’ or LUF.
• In the LUF syndrome, women will have the normal sequence of endocrine events and a normal menstrual period but their ovary will not release the egg.
• Non-steroidal anti-inflammatory drugs give rise to LUF, research has shown.
• In women with LUF syndrome, steroid hormone concentrations in the peritoneal fluid are much lower after the ovulatory cycle. It is felt that this may facilitate the development of endometriosis.– Konnninckx PR, DeMoor P, and Brosens IA, “Diagnonsis of the lutenized
unruptured follicle syndrome by steroid hormone assays on peritoneal fluid” in Eur J Obstet Gynaecol, 87:929-34, 1980
Fertility• “In pregnancy it is known that nutrient requirements alter.
Women on good diets are seen to have healthier babies than those on poor diets”.
– Wynn AHA, Wynn M ‘The Case For Preconceptual Care in Men and Women’ AB Academic Publishers, Bicester, Oxon 1991
• “Riboflavin (B2) deficiency causes hormonal imbalances and is essential for the liver clearance of steroid hormones (oestrodial and progesterone). Deficiency inhibits the LH secretion from the pituitary and GnRH from the hypothalamus. Riboflavin (B2) works closely with vitamin B5 and if levels fall below 80 per cent then the reproductive system fails”.– Esch M.W., Easter R.A., Bahr J.M., ‘Effect of riboflavine deficiency on estrous
cyclicity in pigs’. Biol. Reproduction : 25 : 659-665. 1981
Fertility
• “Low intake of B vitamins may also slow down the ripening of the egg before conception and be affecting fertility. The hypothalamus in other mammals reacts to a severe deficiency of any of these B vitamins by inhibiting GnRH secretion and so causing infertility”.– Watteville H, Jorgens R, Pfalz H, ‘Einfluss von Vitaminmangel auf
Fruchtbarkeit, Schwangerschaft und Nachkommen’ Schweiz Med Wochenschr. 84. 875-882.1954
Research at Hackney Hospital looked at the weights of new babies
• “Mothers of low birthweight babies had been eating meat, meat products, white bread, refined sugars and soft drinks in greater amounts. Mothers of the healthy weight babies had been eating nutrient-rich foods, three regular daily meals, (breakfast being the most important), and wholegrain cereals, muesli, oats, nuts and seeds daily, eggs, egg dishes, wholemeal bread, dairy foods, and lots of fresh fruits and vegetables” (41).
– Doyle W et al, Maternal nutrient intake and birthweight’ in J Hum Nutri Diet, 2:415-22, 1989.
HEALTHY BABIES• Burke et al looked at mothers who had eaten good/excellent
diets, they gave birth to babies judged to be in good/superior health 94 per cent of the time. Contrasted with mothers whose diet were classified as poor and whose infants had good health only 8 per cent of the time.
– Burke BS, Harding VV, Stuart HC. ‘Nutrition studies during pregnancy’. J Paediatrics. 1943 Vol 23; 506-515
• “If the mother’s nutrition stores are inadequate during the time when the placenta is developing, then the placenta will develop poorly. As a consequence, no matter how well she eats later, her unborn baby will not receive optimum nourishment”.
– Aherne W, Dunhill MS. “Morphology of the human placenta’. British Medicine Bulletin. Vol22 (1) 5-12. 1966
Fertility Conclusion
• The conclusion is that a developing embryo/foetus requires abundant nutrients via the placenta, in order to become a healthy bouncing baby.
• High-calorie, empty-nutrient over-refined foods were obviously detrimental to the developing baby in the womb. “The hypothesis of the Hackney study, that the diet of the mothers of low birth weight babies had too few nutrients in their diets was supported”.
– Wynn AHA, Wynn M. ‘The need for nutritional assessment in the treatment of the infertile patient’, in J Nutri Med., 1:315-24, 1990

The importance of sound nutrition on health
– Dr Weston Price, Dr. Francis Pottinger, Sir Robert McCarrison
• It is the quality of food eaten which confers good health on the recipient
• Healthy food was seen to emanate from healthy soil and good farming principles
• We are all biochemically different and that some individuals requirements for nutrients may be different due to body biochemistry
The Nutrient Content of and nutrient availability from the modern food supply is
different from that of palaeolithic times
• Reduction of omega-3 fatty acids from fish• Intensive livestock farming = nutrient deficiencies of
these animals and problems with infections• Intensive farming techniques = soil demineralisation,
overuse of pesticides• Agrichemicals and environmental pollutants find their
way into the food chain• Reduced nutrient content of foods = compromise of
nutritional status = reduction in individual adaptation

Omega 3 and Omega 6 Essential fatty acids and pain reduction
• In a group of Danish women, a higher intake of omega 3 fatty acids or a higher ratio of omega 3/omega 6 fatty acids was associated with reduced Menstrual pain.– Deutch B. Menstrual pain in Danish women correlated with low omega
3 polyunsaturated fatty acid intake. Eur J Clin Nutri 1995;49: 500-16
• Women should reduce their saturated and trans fatty acid intake by half - then oestrogen levels will be around 20% lower
Omega 3 and Omega 6 Essential fatty acids and pain reduction
• Animal fats from meat and dairy foods and manufactured foods should be reduced
• Omega 3, omega 6 and omega 9 cis fatty acids should be eaten to maintain levels of anti-inflammatory prostaglandins PGE1 and PGE3
• Use oily fish, nuts and seeds, dark leafy vegetables, cold-pressed extra virgin olive and walnut oils
Gastric Disorders Survey
• 69% of the population surveyed showed signs of one gastro-intestinal disorder over the previous three months
• In the USA annual medical costs for gastro-intestinal disorders are $41M (£25.6M)
• Constipation affects 4 million Americans each year
• Americans spend $725M a year on laxatives
Gut Flora
• 2-4 lbs of gut bacteria live in the intestines.• 100 trillion organisms make up this flora• 400-500 different species provide an active
metabolic action equivalent to the liver• They provide a protective atmosphere and are a
critical factor in immune stimulation• Antibiotics, oral contraceptives, hormone
replacement therapy and steroids, non-steroidal anti-inflammatories disrupt flora.
Gut Associated Lymphoid Tissue (GALT)
• GALT tissue and Peyers patches exclude all infectious agents, allergenic material, toxic substances from entering the bloodstream
• GALT makes the GI tract the largest lymphoid tissue/immune organ in the body
• 1010 immunoglobulin producing cells per metre of small bowel account for 80% of all immunoglobulin cells in the body
• GALT is the bodies first line of defence against alien invasion
Immune System
• Research has shown that subclinical autoimmune disease may be involved with reproductive failure. “Forty-four per cent of women who miscarried were seen to have antibodies implicated with anti-cardiolipin, it has also been speculated that two thyroid autoantibodies are involved with reproductive failure. Thyroid autoantibodies have been used as as guides to point to women at risk from miscarriage”.
– Singh A, Nery Danta Z., Stone S.C., Asch R.H., ‘Presence of thyroid antibodies in early repproductive failure: biochemical versus clinical pregnancies.’ Fert. and Ster. 1995: Vol 63(2) 277-281
Food Allergies/intolerances
• One man’s meat is another man’s poison
Common allergies - fish, peanuts
• Common intolerances - wheat, bovine dairy, citrus, deadly nightshade family
• Chemicals
• Pollens, dusts, moulds
Immune system
• Research suggesting a link between coeliac disease and autoantibodies to the thyroid warrants further investigation. “Adults tend to present with these problems in their 30’s and 40’s, tiredness, mouth ulcers, malaise, fertility problems and malabsorption being the main problems” (22).
• All women with unexplained infertility should request these very basic tests.– Howard S., ‘Module 16: Current Thinking in Coeliac Disease:’ Pharmacy
Magazine Feb. 1997: CEI - CEVIII
Dietary Strategies
1. Substantial breakfast - some of the following:wholegrain cereals, eggs, nuts, seeds, fruits, dairy foods
