    The role of cervical mucus-semen interaction in infertility of unknown aetiology (1984)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 91 (1984), S. 0

    Notizen: An in-vitro penetration assay, which incorporates measurements of sperm motility and forward velocity, was used to investigate sperm-cervical mucus interaction in 20 couples with unexplained infertility. Evidence of impaired cervical mucus penetration was found in this group of patients and in seven couples the results correlated with previous assessment by laparoscopic sperm recovery. The impairment of cervical mucus penetration was found to be due to defective sperm function rather than to the quality of the cervical mucus itself. Of the criteria of semen quality measured in this study, sperm motility and the zona-free hamster egg penetration test showed significant correlations with cervical mucus penetration.

    A RAPID LUTEINIZING HORMONE RADIOIMMUNOASSAY FOR THE PREDICTION OF OVULATION (1981)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 88 (1981), S. 0 
    Details
    ISSN: 1471-0528
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: A rapid luteinizing hormone (LH) radioimmunoassay (total time 4 h) has been developed and used to measure the preovulatory LH surge in 22 patients. Ovulation, assessed by laparoscopy or mini laparotomy, did not occur until at least 32 h after the start of the LH surge. This rapid LH radioimmunoassay provides a simple method of predicting ovulation for the correct timing of oocyte collection or artificial insemination.

    Relation between the luteinizing hormone peak, the nadir of the basal body temperature and the cervical mucus score (1982)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 89 (1982), S. 0 
    Details
    ISSN: 1471-0528
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: Summary. The results of a cervical mucus scoring system and of basal body temperature (BBT) chart interpretation were compared with those of a short-incubation radioimmunoassay for luteinizing hormone (LH) in 198 ovulatory menstrual cycles. The timing of the maximal cervical mucus score was similar to that of the LH peak in all but 7% of assessable cycles. In contrast, the timing of the nadir of the BBT differed widely from that of the LH peak in 45% of cycles with interpretable charts. These findings suggest that cervical mucus scoring might be useful for identifying the time of ovulation where LH assays are unavailable or where speed and economy are at a premium.

    Hysterectomy following sterilization (1982)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 89 (1982), S. 0 
    Details
    ISSN: 1471-0528
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: Summary. Using record linkage data derived from Scottish hospital discharge summaries, admissions to gynaecological units and hysterectomy rates have been studied following sterilization. The average annual gynaecological admission rate per 1000 women was 43·7 in the group of sterilized women and 21·5 in the control subjects. The average annual hysterectomy rate was 9·3 in the sterilized women and 2·5 in the control subjects. Although there were differences in age and pregnancy number between cases and controls, these did not account for the observed differences. This study was not able to determine whether the increase in gynaecological morbidity was due to the sterilization procedure or to the characteristics of the women sterilized.

    LAPAROSCOPIC SPERM RECOVERY IN INFERTILE WOMEN (1980)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 87 (1980), S. 0 
    Details
    ISSN: 1471-0528

    Thema: Medizin
    Notizen: Sperm recovery from the peritoneal fluid was attempted in a group of infertile women in whom it was anticipated that all routine investigations would be normal (commonly referred to as ‘normal infertiles’). Forty-four couples were recruited into the study but in retrospect only 24 met the study criteria of normal semen, normal pelvis and appropriate timing. In 15 of these 24 patients, spermatozoa were covered from the peritoneal fluid, and so far seven have become pregnant. In the nine patients where spermatozoa were not recovered, none have so far become pregnant. There was no correlation between sperm recovery and the quality of the post-insemination cervical mucus examination. This test allows more accurate assessment of the ability of spermatozoa to reach the site of fertilization.

    Notizen: [Auszug] Details of the volunteer egg donors are given in Table 1. One woman had experienced 6 yr of unexplained primary infertility (case 1) and six women were undergoing laparoscopic sterilization. The volunteer sperm donors were healthy males (their ages are listed in Table 1). All the participants were ...
