Vaginal malformations.

Of 254 patients with vaginal malformations, 167 had total vaginal agenesis and 87 had lesser defects. Incidence, embryogenesis, etiology, and associated anomalies are described. Improvements in surgical management have diminished complications and improved results. Preoperative investigation and preparation of the patient and prolonged postoperative supervision and support are critical.

Impact of the stress of AID on the menstrual cycle.

Reports by others that stress surrounding AID alters the menstrual cycle has prompted some physicians to provide pharmacologic control to predict the day of ovulation. We studied the BBT charts of 47 women who had predictable menstrual cycles in the 2 months preceding AID in order to compare them with day of ovulation and length of luteal phase of the 1st month of AID. Although there was a significant difference in the day of ovulation between AID and non-AID months, the difference was less than 1 day. We did not find the large shift in ovulation day during the 1st month of AID reported by others.

Stability of basic semen measures and abnormal morphology within individuals.

Semen from 15 healthy volunteers was assessed for basic semen measures every 2 weeks over a 6-month period to determine the relative stability of these factors. The parameters were: sperm count, semen volume, sperm motility, and normal morphology, along with the type of abnormal morphologic forms. Basic semen measures were generally more stable than the morphologic forms. Using three samples, seven semen factors (sperm count, normal morphology, semen volume, sperm motility, microcephaly, tapering and round tail) were found to be stable and contributed to the identification of the fifteen individuals with a classification accuracy of 75.0%. While individuals do have characteristic patterns of spermatogenesis, the biologic basis for these findings is as yet undetermined.

Development of a paraprofessional home visiting program for low-income mothers and infants.

This article reports the development of a paraprofessional home visiting program based upon empirically documented client needs, maintenance of the qualities of mutuality and cooperation found in the indigenous paraprofessionals, and methods of ongoing program revision. Three studies are described that suggested four areas of program emphasis: (1) continuity of services from pregnancy through infancy, (2) needs assessment procedures sensitive to a broad range of health and social problems, (3) an ongoing personal relationship with an indigenous paraprofessional, and (4) reduction of barriers to prenatal care inherent in the health care system itself. We provide examples of program application and revision through training of paraprofessionals, case management procedures, and interventions within the perinatal health care system.

Effect of stress on semen quality in semen donors.

Fifty-three donors with good semen quality were studied monthly for sperm count and motility over 9 to 22 months. Medical students (n = 31) in freshman and sophomore years subjected to the stress of twice-yearly examinations were compared with nonstudents (n = 22) not exposed to common stressful periods. Sperm count and quality (count X motility) for the student group were significantly elevated during examination months versus nonexamination months. Controls demonstrated no differences over these months. Differences between individuals, donor selection factors, and the effects of variable degrees of stress on sperm transport may have contributed to this finding.
