Sexual and reproductive health experiences and care of adult women with cystic fibrosis

Kazmerski TM et al., 2023 J Cyst Fibros

As survival and health improve in people with cystic fibrosis (CF), more women with CF (wwCF) are considering their sexual and reproductive health (SRH). This study compared SRH experiences, behaviors, and care utilization of wwCF to the general population and defined CF-impacted considerations and care preferences. We surveyed wwCF aged ≥25 years regarding SRH and compared results to the US National Survey of Family Growth (NSFG;n = 4357) and friend controls(n = 123). We used descriptive statistics and chi-squared/Fisher's exact testing and linear regression for comparisons. A total of 460 wwCF (mean age 36.1 years) completed the survey. WwCF were less likely to report current contraceptive use (43%vs76% NSFG, p<0.001;60% friends, p = 0.005). Nearly 25% of wwCF reported worsened CF symptoms during their menstrual cycles, 50% experienced urinary incontinence, and 80% vulvovaginal candidiasis. WwCF were significantly less likely to be parents (46%vs62% friends, p = 0.015) and to have experienced pregnancy (37%vs78% NSFG, p<0.001;58% friends, p = 0.002). More wwCF required medical assistance to conceive (29%vs12% NSFG, p<0.001 and 5% friends, p<0.001). Eighty-four percent of wwCF view their CF doctor as their main physician and 41% report no primary care provider (vs19% friends; p<0.001). WwCF report suboptimal rates of contraceptive and preconception counseling/care and are less likely to have received HPV vaccination (42%vs55%friends, p = 0.02). Despite desiring SRH conversations with their CF team, <50% report discussing SRH topics. WwCF have significantly different SRH experiences than non-CF peers. They report suboptimal SRH care compared to their preferences highlighting an urgent need to encourage SRH counseling/care in the CF model.

Natural family planning. Natural methods have cross cultural appeal

Methods · Billings Ovulation Method

The validation of the Billings ovulation method by laboratory research and field trials

Billings JJ, 1991 Acta Eur Fertil

Fertility and the mechanism of ovulation is complex. The processes of fertilization and ovulation are described in this report. Information includes a description of the natural indicators of fertility and infertility, the cervical mucus pattern, and the Guidelines for the Billings Ovulation Method. The ovarian monitor which provides for the measurement of ovarian hormones (estrone glucuronide (EIG) and pregnanediol glucuronide (PdG) in a timed specimen of urine is also described. The cervical mucus pattern method measures ovarian hormones and fertility. No more than 2% of women who have been taught the Ovulation Method and performed the charting would need to use the Ovarian Monitor. It is commonly used to assure that the women's observations and interpretations are correct when there is a strong desire to either achieve or postpone pregnancy. For research, the monitor is useful in accurately measuring the timing of ovulation within the phase of potential fertility during the cycle and the changing probabilities of conception on days within the fertile period. The limits of the fertilizing life span of sperm can be measured as well as the factors which influence this life span. The day of maximum fertility, the correlation of the mucus pattern with fertility and time of ovulation, and assessment of conception cycles are measurable. Diagnostic information can be gleaned which will help to explain bleeding patterns, particularly around menopause, where fluctuating ovarian hormonal levels influence unexplained bleeding patterns. The Monitor can be useful as a test for pregnancy in measurement of high PdG and E1G levels. Four phases are identified for interpreting the ovulatory cycle: 1) the E1G and PdG levels are declining during the beginning of menstruation to reach a constant level (20-60 nmol/24 hours and .9 - 3.3 mcmol/24 hours); 2) rising E1G values and low PdG values and changing mucus pattern of the preovulatory cycle; 3) the ovulatory phase of peak E1G values (150-450 nmol/24 hours) followed by a distinct fall and the beginning of a rise in PdG values and the Peak of the mucus pattern; and 4) the luteal phase of rising PdG (9-36 mcmol/24 hours), and rising E1G values (100-400 nmol/24 hours) to maximum, and then falling before menstruation.

The Billings Ovulation Method. An update

Billings JJ et al., 1988 Aust Fam Physician

Women can accurately predict the day of ovulation by examining vaginal mucus using the Billings Ovulation Method (BOM). they then can choose to either have sexual intercourse if they wish to conceive or to refrain if they do not want to become pregnant by being able to identify the peak day of fertility and the 3 following days of diminishing fertility. A preovulatory phase of the ovulatory cycle follows menstruation which generally includes a sensation of dryness around the genital area but sometimes no dry days occur. At this point progesterone activates the secretion of a thick sticky mucus into the cervical canal which sperms cannot penetrate. This mucus also serves to guard against infection in the reproductive tract and abdominal cavity. When circulating estrogen increases due to follicular development a fluid clear and stringy mucus replaces the thick mucus. this mucus is like a raw egg white. Under the microscope it has a distinctive fern pattern. Sexual intercourse during this time period may result in pregnancy because this mucus sustains sperm cells in cervical crypts for 48-72 hours. Not all women notice the changes in the mucus however but they can sense the vulva as soft swollen and moist. The final day of this sensation identifies the peak day (day 1) in which ovulation customarily occurs. Even though fertility decreases in the next 3 days conception may occur in days 1-3. Infertility sets in on day 4 and last on average 2 weeks. any mucus now seems sticky and opaque. WHO field trials in El Salvador and 4 other countries confirmed that BOM is >99% effective when couples adhere to the guidelines. Research demonstrated that illiterate couples from low socioeconomic status understand it and apply it successfully.

Biomarkers · Urinary Hormone Monitoring

Natural family planning

Brown JB et al., 1987 Am J Obstet Gynecol

It is now well accepted that a woman can conceive from an act of intercourse for a maximum of only about 7 days of her menstrual cycle. The reliability of natural family planning depends on identifying this window of fertility without ambiguity. Several symptomatic markers, cervical mucus and basal body temperature, have been used extensively and with considerable success in most women but failures occur. Ovarian and pituitary hormone production show characteristic patterns during the cycle. Urinary estrogen and pregnanediol measurements yield reliable information concerning the beginning, peak, and end of the fertile period, provided that the assays are accurate and performed on timed specimens of urine. We have developed such enzyme immunoassays for urinary estrogen and pregnanediol glucuronides that can be performed at home. In the early versions of the assays, enzyme reaction rates were measured by eye, but more recently, a simple photoelectronic rate meter has been used. The final problem to be solved is not technologic but whether women are sufficiently motivated to expend the same time and effort each day for 10 days a month, with less cost, on fertility awareness as they spend on making a cup of tea.

Biomarkers · Cervical Mucus

Cervical mucus as a biological sign of fertility and infertility

Billings JJ, 1984 Contracept Fertil Sex (Paris)

The ovulation method makes women aware of certain changes in their cervical mucus. These modifications help to distinguish the beginning and end of the cycle's fertile period and indicate the time of maximum fertility. In addition to pinpointing the date of ovulation, the method permits the user to know she is not fertile when there is no ovulation. The principle of the method is the state of "basic infertility" which preceeds follicular development. The method cannot be implemented with success unless it is properly acquired. After some preliminary considerations regarding the fertile period, ovluation detection and periodic abstinence, some clinical and hormonal observations are compared in 2 basic studies in order to show to what extent cervical mucus reflects ovarian activity. The application of the method requires an understanding of the "basic infertility profile" and 2 sets of rules regarding the 1st days and the peak sign which indicate respectively the beginning and end of the fertile period. The criteria of an ideal birth control method and the importance of proper teaching are also dealt with. With regard to Natural Family Planning, 2 problems are pointed out--incomplete terminology in data collection and absence of a positive and detailed approach to periodic abstinence.

Effectiveness · Typical and Perfect Use

Natural family planning methods

Billings JJ, 1982 Am J Obstet Gynecol

Wade et al.'s report, entitled "A randomized prospective study of the use-effectiveness of 2 methods of natural family planning," contains items worthy of emphasis. These includes the following: 1) less than 5% of the women in the study were prevented from using the method assigned them because of problems in identifying their cervical mucus pattern; 2) those who were unable or unwilling to adhere to the methodology were encouraged to drop out; 3) the largest single category of pregnancies occurred in both groups when the volunteers failed to follow the rules for avoiding pregnancy; 4) it was judged that there were 6 pregnancies in the ovulation method group to be classified as method failures, apparently for a total of 4501 cycles, which gives a method-failure rate of 1.6%; 5) couples were required to sign an informed consent statement of their awareness that the chances of the occurrence of pregnancy could be as high as 25% for the ovulation method; 6) recruiting difficulties constituted an important finding, primarily because they were unexpected by the investigators; 7) the volunteers recruited into the trial were restricted to those women whose menstrual cycles were 24-36 days; 8) the couples who failed to continue with the use of these 2 natural methods--ovulation and temperature rhythm--were on the average younger, more sexually active, and had fewer children; and 9) the ovulation method brings the partners into confrontation with their fertility in each cycle, and this has marked psychological results, including an awakening of the suppressed desire for that fertility to become creative of human life.

Cervical mucus: the biological marker of fertility and infertility

Billings JJ, 1981 Int J Fertil

The ovulation method provides a woman with an awareness of her cervical mucus pattern. This enables her to mark the beginning and end of the fertile phase of the cycle as well as the time of maximum fertility. Not only is the time of ovulation located but also there is recognition of infertility in the absence of ovulation. The key to understanding is the concept of the basic infertile pattern which precedes the commencement of follicular development; the key to successful use is competent teaching. After preliminary considerations on the fertile phase the determination of ovulation and the aspect of periodic abstinence two basic studies comparing clinical and hormonal observations are reviewed showing how accurately the cervical mucus reflects ovarian activity. Understanding the basic infertile pattern and the two sets of rules (the early day rules and peak rule identifying respectively the beginning and end of the fertile period) is basic to the application of the ovulation method. Criteria for the ideal family planning method and the importance of quality teaching are presented. Two problems requiring attention in NFP are restrictive terminology in data collection and a lack of fully developed and positive approach to periodic abstinence.

Oral Contraceptives · Metabolic Effects

Strokes and contraceptive medication

Currie JN et al., 1980 Med J Aust

3 cases of stroke in young women of childbearing age are presented to show the severity of illness and mortality in women using oral contraceptives. All 3 patients smoked more than 15 cigarettes a day. The mortality rate from cerebrovascular disease in OC users has been estimated as 4.7 times that of nonusers. The risk of developing a thrombotic stroke is 9.5 times greater than a control group's. Cerebral infarction has a relatively low mortality rate in young women, 9%, but a nonfatal stroke can have a devastating effect on the patient and her family. While there were no deaths among the 3 cases, each was left with a varying degree of neurological deficit while still in the peak of a normal life span. The possibility of synergistic potentiation of OC-associated cerebral thrombosis by cigarette use is uncertain but studies have noted some correlation between the 2. It is not clear that reduction in estrogen dosage has reduced the risk of cardiac or cerebral disease. The first patient developed extreme symptoms after a heavy drinking session, thereby raising the question of alcohol as a precipitating factor.

Natural family planning

Billings JJ, 1978 P N G Med J

Pip: The only way to be sure of avoiding pregnancy is for a couple to abstain from sexual intimacy during the fertile phase of the woman's cycle. Billings showed by reference to hormonal parameters that after competent instruction in the ovulation method women can identify the fertile phase of their cycle. If abstinence during the fertile phase is replaced by coitus combined with barrier methods, the pregnancy rate will be higher. The hormonal monitoring has revealed that the Peak Symptom as defined in the ovulation method is the most accurate biological marker of the time of ovulation. The cervical mucus pattern reflects the estrogen levels during follicular ripening from its commencement, and the Peak Symptom reflects a sharp cut-off effected by the elevation of the progesterone level at the time of ovulation. This means that once the mucus begins to be observed as a warning of the approach of ovulation, the woman needs to follow the changing characteristics on a daily basis in order to be certain that she recognizes ovulation.
