The prevalence, risks, and management of Chlamydia trachomatis infections in fertile and infertile patients from the high socioeconomic bracket of the South African population

Practice patterns among reproductive endocrinologists: the infertility evaluation

OBJECTIVE

To determine how board-certified reproductive endocrinologists vary in their approach to the clinical tests performed on the infertile couple.

DESIGN

A cross-sectional study to assess differences in the approach to evaluating the infertile couple.

SETTING

A population-based national survey.

PARTICIPANT(S)

United States board-certified reproductive endocrinologists.

MAIN OUTCOME MEASURE(S)

The frequency of clinical tests and evaluation procedures by physician age, sex, size and setting of practice, institutional affiliation, and geographic location.

RESULT(S)

The overall response rate was 84%. Although the majority of practitioners routinely order a semen analysis (99.9%), an assessment of ovulation (98%), a hysterosalpingogram, (HSG; 96%), laparoscopy (89%), and a postcoital test (PCT, 79%), there was less agreement regarding hormonal testing (range, 22% [LH] to 66% [PRL]), use of pelvic ultrasounds (55%), hysteroscopy (53%), cervical cultures (range, 24% to 54%), and antisperm antibody testing (24%). Compared with male colleagues, female physicians order two to three times more cervical cultures and endometrial biopsies. Serum hormonal testing was two to three times more commonly ordered by younger (< 40 years) compared with older physicians, and physicians in private practice twice as frequently ordered hormonal testing, cervical cultures, PCTs, and antisperm antibody studies compared with their academic-affiliated colleagues. Western U.S. physicians order hormonal tests and cervical cultures 50% less often than their midwest and eastern counterparts.

CONCLUSION(S)

Trained specialists rely heavily on five "traditional" infertility tests: semen analysis, an assessment of ovulation, HSG, laparoscopy, and PCT. With regard to additional modes of testing, there is marked variability by physician sex, age, type of practice, and geographic location.

Urbanisation, household composition and the reproductive health of women in a South African city

Post-apartheid South Africa is faced with the effects of a distorted urbanisation process. A coherent response to urbanisation includes the mitigation of the adverse health effects of urbanisation. Women, by virtue of the stringent control of their movements to urban areas under apartheid, have migrated to the urban areas at an increasing rate recently. One consequence has been the transformation of traditional household structures consonant with changing patterns of fertility and infertility in the urban areas. This paper describes the composition of households in Khayelitsha, South Africa, a suburb that has seen an explosive increase in population over a 5-year period, from 5000 to an estimated 250,000 people. A survey of 659 households revealed the woman-headed households increased from 11% in those women who had been in the urban areas for fewer than 5 years, to 35% in those who had been in the urban areas for more than 20 years. This was not a function of widowhood or divorce, but appears to be an adaptive strategy adopted by women in the face of gender oppression in a harsh urban environment. The study also revealed the phenomenon of "alliance" household formation, in which atypical households made up of a variety of non-descript combinations of people provide support for women from remote rural areas, another adaptive strategy. Fertility was related to age, income, education and urbanisation. Women who had been in the urban areas for longer than 10 years had a total fertility rate (TFR) of 2.5, while those who had been in the urban areas for less than 10 years had a TFR of 5.8. Reported infertility was related to marital status, education, gynaecological illness and urbanisation, with recently urbanised women reporting more infertility. This probably reflects the different expectations of rural women and changes the mix of attitudes to fertility in the urban areas substantially. These findings have major implications for population policies in South Africa and an eclectic mix of approaches, including small area-specific approaches, to family spacing is recommended.

Chlamydia trachomatis antibody titers and hysterosalpingography in predicting tubal disease in infertility patients

OBJECTIVE

To determine if the number of diagnostic laparoscopies done on women without tubal adhesive disease could be reduced by testing for tubal disease with Chlamydia trachomatis antibody titers and hysterosalpingography (HSG), either singly or together.

DESIGN

Historical prospective chart review.

SETTING

The Colorado Kaiser Permanente Reproductive Endocrinology Clinic.

PATIENTS

All 703 infertility patients who had C. trachomatis antibody titers done from March 2, 1988 to April 30, 1992. The final study group was comprised of 218 patients who had antibody titers, HSG, and laparoscopy.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Sensitivity, negative predictive value, and false-positive rate were the test characteristics of interest. Tubal disease was identified by laparoscopy.

RESULTS

For HSG testing, the sensitivity was 78% and the negative predictive value was 85%. For C. trachomatis titers, the sensitivity was also 78% and the negative predictive value was 82%. Ninety-five percent confidence intervals for sensitivity and negative predictive value overlapped, indicating that there was no significant difference. However, false-negative rates were the same for the two tests, but false-positive rates were lowest for HSG and series testing.

CONCLUSIONS

To minimize false-positive tests and thus, to minimize unnecessary laparoscopies, HSG testing either alone or combined with the C. trachomatis antibody titer as series tests yielded a significantly lower false-positive rate. In our study group, if both tests were negative, tubal disease was identified on laparoscopy in only 5% of cases. Choice of most cost-effective test sequence will depend on who bears the cost. Further studies of cost-benefit using well-defined testing sequences are needed to determine if C. trachomatis antibody titers in series with HSG would be more cost effective than HSG alone in detecting tubal disease.
