2 Billings Ovulation Method Natural Fertility Regulation

3 Billings Ovulation Method A natural way to: Achieve Pregnancy Postpone Pregnancy Monitor Reproductive Health

4 Billings Ovulation Method easy to learn simple to use no drugs or devices no side effects reliable morally acceptable to all cultures

5 Male Fertility Sperm production begins at puberty Production of sperm continues throughout life Female Fertility Begins from puberty Cyclic – potentially fertile for approx 5-7 days Finishes at menopause + = Couple Fertility

6 THE FEMALE REPRODUCTIVE ORGANS

7 THE OVARIES – whose function is the cyclic maturation of ova (eggs), produce hormones oestrogen and progesterone

8 FALLOPIAN TUBES – tubes through which sperm cells are assisted in their passage from the uterus to the ovum (egg)

9 FALLOPIAN TUBES – the fertilized ovum (embryo) is actively transported to the body of the uterus

10 THE UTERUS - the organ of the female in which the embryo implants and develops

11 ENDOMETRIUM – the inner lining of the uterus which is shed at menstruation

12 THE CERVIX – the neck of the uterus which bears the mucus-producing crypts

13 THE VULVA – the external parts of the female genital organs. It is the sensing organ for cervical mucus

14 THE VAGINA – the birth canal, the passage through which the baby is delivered The lining of the vagina has no glands

15 POCKETS OF SHAW – after ovulation, under hormonal control, mucus is dried as it passes through the vagina

16 Keeping a Record Observations made at the vulva as the woman goes about her normal daily activities No internal examination Most fertile characteristic of day recorded each evening One or two words recorded to describe sensation and appearance Coloured stamps or symbols used on chart

17 The woman will both feel and see the bleed as it arrives at the vulva

18 Sensation/ Appearance of discharge Menstruation, indicated by a red stamp or the symbol 

19 Following menstruation cervix occluded with thick, dense plug of mucus

20 Plug prevents passage of sperm into cervix and protects body from infection Sperm cells kept out in vagina quickly become incapable of fertilizing ovum and destroyed by surrounding cells

21 The ovaries are quiescent Nothing leaving the cervix, vulva feels dry

22 DRY - nothing is felt, nothing is seen Recorded with a plain green stamp or the symbol | BASIC INFERTILE PATTERN (BIP) UNCHANGING PATTERN - DRY

23 Discharge remains same day after day, cycle after cycle Small fragments breaking off lower part of plug results in discharge BASIC INFERTILE PATTERN (BIP) UNCHANGING PATTERN - DISCHARGE

24 Basic Infertile Pattern of mucus remains the same day after day, cycle after cycle. Initially recorded with white baby stamp or the symbol O Then recorded with yellow stamp or the symbol = when pattern is seen to be unchanging

25 Basic Infertile Pattern of mucus remains the same day after day, cycle after cycle. Three cycles are studied in order to identify correctly the point of change of sensation or appearance of the mucus or both

26 Basic infertile pattern of mucus remains the same day after day, cycle after cycle. There is no entry of sperm into the cervix because of the plug of mucus This unchanging pattern of infertility is common for many women

27 Ovaries are active and are producing oestrogen Cervix is stimulated – fluid mucus is produced, this frees the plug, sperm can now enter cervix oestrogen

28 Change in sensation – no longer dry Recorded with white baby stamp or symbol O

29 Ovaries are active and are producing oestrogen Cervix is stimulated – fluid mucus is produced, this frees the plug, sperm can now enter cervix Change in vulval sensation or appearance of mucus

30 Changing pattern of fertility Ovaries producing greater amounts of oestrogen Mucus progressively changing to a wet, slippery sensation Clear strings of mucus may be noticed CHANGING PATTERN OF FERTILITY

31 Maximum amount of mucus may diminish Slippery sensation may continue for a day or two Last day of slippery sensation the most fertile day of the cycle - PEAK OF FERTILITY Very close to the time of ovulation CHANGING PATTERN OF FERTILITY

32 THE PEAK the last day of the slippery sensation associated with increased sensitivity and with swelling of the vulva

33 THE PEAK The ovary is now producing progesterone, preparing follicle to shed ovum (ovulation) progesterone oestrogen

34 RECOGNISING THE PEAK Peak is recognised on the day of change No longer any lubricative sensation at the vulva Peak is marked with a cross on the record

35 Ovulation occurs on Peak day or days 1 or 2 after Peak The ovum can live for up to 24 hours

36 DAY 1 to 3 PAST PEAK Cervix gradually closes with thick plug of mucus Small channels remain through which sperm can travel

37 The three days following the Peak are marked with a numbered green or yellow baby stamp or a numbered symbol | or = DAY 1 to 3 PAST PEAK

38 THE LUTEAL PHASE From the fourth day past Peak, cervix is closed Sperm cannot enter If not fertilized, the egg will have disintegrated

39 THE LUTEAL PHASE Plain yellow or green stamps are now used or the symbols = for discharge or | for dry

40 Occurs days after ovulation Plug has left the cervix allowing flow of blood Start of next cycle MENSTRUATION

41 Billings Ovulation Method 3 Early Day Rules Peak Rule 4 Rules

42 Early Day Rule 1 Avoid intercourse on days of heavy bleeding during menstruation.

43 Early Day Rule 1 Reason: Ovulation might occur quite early in the cycle and menstrual bleeding could obscure mucus

44 Early Day Rule 1 Ovulation can occur as early as day 5 Menstrual bleeding would obscure beginning of fertile phase

45 Early Day Rule 2 Alternate evenings are available for intercourse when these days have been recognised as infertile. (Basic Infertile Pattern)

46 Early Day Rule 2 Reason: If the woman is lying down the fluid mucus that leaves the cervix in the beginning of the fertile phase, collects in the upper part of the vagina. The woman needs to be in an upright position for a few hours for this cervical mucus to make its presence felt at the vulva. Seminal fluid on the day following intercourse could obscure the mucus. It is important to allow time for the seminal fluid to disappear and to confirm the BIP is still present by avoiding intercourse on consecutive evenings.

47 Early Day Rule 2 Alternate evenings are available for intercourse when these days have been recognised as infertile. (Basic Infertile Pattern)

48 Early Day Rule 2 Alternate evenings are available for intercourse when these days have been recognised as infertile. (Basic Infertile Pattern)

49 Early Day Rule 3 Avoid intercourse on days of discharge or bleeding which interrupts the Basic Infertile Pattern. Allow 3 days of BIP afterwards before intercourse is resumed on the fourth evening. Rule 2 continues

50 Early Day Rule 3 Reason: Waiting will enable the woman to either recognise the Peak in which case the Peak Rule is used……………….

51 Early Day Rule 3 Waiting will enable the woman to either recognise the Peak in which case the Peak Rule is used, or ……………………

52 Or when the change is an interruption of the BIP caused by raised oestrogens, the hormonal level will return to a basic low level and the woman will recognise a return of the BIP. She counts 3 days to enable the oestrogens to settle at the basic low level, before resuming intercourse applying Early Day Rule 2

53 Early Day Rule 3 or when the change is an interruption of the BIP, caused by raised oestrogens…… Allow 3 days of BIP before intercourse is resumed on 4th evening

54 Peak Rule From the beginning of the 4 th day past the Peak until the end of the cycle, intercourse is available every day at any time.

55 Peak Rule From the beginning of the 4 th day past the Peak until the end of the cycle, intercourse is available every day at any time.

56 Billings Ovulation Method Observation of Patterns Fertility Changing, developing pattern of variable lengthInfertility Unchanging pattern

57 Rules for achievement of Pregnancy Apply the Early Day Rules Postpone intercourse until the slippery sensation occurs Intercourse should occur over the time of the slippery sensation and for one or two days after

58 Rules for postponement of Pregnancy Apply The Early Day Rules The Peak Rule

59 Billings Ovulation Method 3 Early Day Rules Peak Rule 4 Rules Can be used throughout all stages of reproductive life

60 Billings Ovulation Method Effectiveness Recent trials have reported effectiveness greater than 99% when the Method guidelines were followed for avoidance of pregnancy * *Indian Council of Medical Research Task Force on NFP (1995) *Jiangsu Family Health Institute, China (1997)

61 Billings Ovulation Method Requirements Accurate Observations Accurate Charting Motivation Loving co-operation

62 Billings Ovulation Method Benefits Accurate, scientific, simple method of regulating fertility Increases knowledge, understanding and of respect for fertility Joint responsibility Does no harm Develops couple communication and relationships

63 Billings Ovulation Method Research began in Ongoing research has confirmed validity of this safe, effective and reliable method Drs John and Evelyn Billings
