Comparison of three different models of the copper T intrauterine contraceptive device.

A random sequential comparative study of three models of the Copper T intrauterine contraceptive device (IUD) was undertaken in 1,792 women. For 7 months, the TCu 300 and TCu 220C were randomly inserted, and then the TCu 380A and 220C were randomly inserted for the next 12 months. The log-risk method of life-table analysis of event rates was performed at the end of each of the first 3 years of use of each device. The TCu 380A had the lowest pregnancy rate during each year of use, although the difference was not significant. At the end of each of the first 2 years, the TCu 300 was removed significantly less than the TCu 220C and TCu 380A for bleeding and pain. At the end of three years, the rates of removal for bleeding and pain for the TCu 380A and TCu 300 were similar and lower than that for the TCu 220C, but the overall difference was not significant. There were no differences among the devices for any other relevant use-related reasons. The TCu 380A was removed for other medical reasons significantly more frequently than the other devices at the end of 2 and 3 years. Adjusting for parity did not alter the results. The findings of this study suggest that the copper sleeves along the horizontal arms together with copper wire on the vertical arm in the TCu 380A model provide greater protection against intrauterine pregnancy, whereas the copper sleeves along the vertical arm as in the TCu 220C caused increased removals for bleeding and pain. The TCu 380A should be studied in a larger number of patients for a longer period of time to determine its clinical effectiveness. It may become the IUD of choice for all women irrespective of parity.

Increase in diaphragm use in a university population.

A striking increase observed in the demand for the diaphragm method at a contraception clinic for university women was documented by means of a record review and questionnaire. Record reviews completed at the conclusion of each semester from December 1973 to December 1976 showed a statistically significant increase in diaphragm acceptors. In the fall semester of 1976, diaphragm acceptors (49% of 151 patients) surpassed pill acceptors (46%). Data from 123 questionnaires revealed that concern for pill and IUD side effects was the primary reason for diaphragm choice. The study numbers are small, but a definite trend is evident. These educated young women may be forerunners, and an increase in diagphragm use in the general population may be seen in the near future.

The effect of intrauterine progesterone on the DNA-content in isolated human endometrial cells.

The effect of an intrauterine progesterone-releasing device on the DNA-content in human endometrial cells has been studied by means of a microfluorometric method. Following six of seven months' use of the progesterone-releasing device a significant decrease in the mean DNA-content per cell nucleus was found in the epithelial cells indicating a suppression of the proliferative activity of the endometrium. The mean DNA-values of the endometrial cells remained at a low level throughout the cycles in spite of circulating levels of steroids indicating a normal ovarian function. It is suggested that the progesterone released in utero interferes with the DNA-synthesis of the epithelial cells, which may result in a disturbed metabolic function of the endometrium at the time of implantation.

The influence of acetylsalicylic acid and paracetamol on menstrual blood loss in women with and without an intrauterine contraceptive device.

The influence of ASA and paracetamol on menstural blood loss and on some hematologic parameters was investigated in 23 women without an IUD and 10 women with an IUD. Neither in women with normal nor in women with small defects in the hemostatic mechanism were statistically significant increases in menstrual blood losses observed during treatment with ASA or paracetamol when compared to placebo. There was no linear correlation between bleeding time and basal menstrual blood loss or between the blood losses induced by ASA and paracetamol and the bleeding time.

Contraception and cervical colonization with mycoplasmas and infection with cytomegalovirus.

The relationship of cervical colonization of genital mycoplasmas and infection with cytomegalovirus (CMV) was studied in 66 intrauterine device (IUD) users as contrasted to 60 patients using oral contraception and 50 patients using neither an IUD nor oral contraception. No significant increase in colonization or genital mycoplasmas or infection with CMV was noted in IUD users. No CMV was isolated from users of the cooper-t IUD. It is unlikely that genital mycoplasmas are related to either the increased immunoglobulin levels seen in patients using the IUD or the antifertility effects of the IUD.

[Endometrial cytology and copper containing intrauterine devices].

Copper-containing intrauterine devices (IUDs) for contraception are increasingly used within recent years. IUDs in situ provoke a non-specific inflammatory cell reaction, particularly at the glandular epithelium of the endometrium. The cellular changes include swelling of the cytoplasm and of the nuclei, the latter showing chromatin clumping, prominent nuclei and a pseudoeosinophilic reaction. Cytoplasmic changes exhibit vacuolation, incorporation of leukocytes and plasmolysis varying in degree. The local inflammation also accounts for the side effects associated with the device, such as uterine bleeding and endometritis. Cytomorphologically, the differentiation between cellular inflammation through IUDs and inflammatory metaplasia is difficult, particularly if the investigator has no information about the presence of an IUD. Intrauterine application of proteinase inhibitors can be helpful in differential diagnosis of such IUD-mediated cellular changes.

Effect of prior pregnancy and combined oral contraceptives on baseline menstrual blood loss and bleeding response to intrauterine devices.

No effect of pregnancy was found on baseline menstrual blood loss (MBL) in women within one year of parturition or abortion. The increased bleeding response of women to intrauterine devices (IUDs) was found to be independent of pregnancy status during the year preceding IUD sertion. Women pregnant within a year of insertion had no different MBL than those pregnant more than a year prior to insertion. MBL quantified in subjects within three months of discontinuing combined oral contraceptives (OCs) was significantly lower than in prior non-OC users. Furthermore, MBL was significantly reduced in the former group during the first three menses following IUD insertion. At the sixth and twelfth menses post-insertion, MBL was still lower in prior OC users, but the difference between users and non-users was less and no longer statistically significant.

A comparative study of the effect of the Progestasert TM and Gravigard IUDs on dysmenorrhoea.

Data obtained from questionnaires on the occurrence of dysmenorrhoea in women using IUDs inserted randomly (146 of them Progestasert and 149 Copper 7) are analyzed. In both groups a reduction in the intensity of menstrual cramps was observed over 12 months of use. Although these reductions are significant in each group, they are slightly higher in Progestasert users. However, on comparing the reduction tendencies of both groups, the difference between them is not significant. No significant differences become apparent either when comparing premenstrual and intermenstrual camps. The usefulness of simple questionnaires directed at detecting the nature of pain in currently used family planning forms for IUD users is discussed.

[Clinical, bacteriological and histological studies following several years of IUD use for contraception].

It is informed about clinical, bacteriological and histological examinations of 108 women who had used IUD's for 2 years. The examinations were carried out on the IUD and on the endometrium. We made use of the transcervical technic of taking out under sterile conditions. Pathological findings could only be fixed amongst 4 women in clinical view. In bacteriological view numerous germs of quite different kind were found at the same patient. Optional pathological germs as they also exist in the cervix were predominant. Of an infection was only spoken if in correspondence of the total material the same germ was found. This concerned only in 6% of the women. Histologically adequate findings resulted. Genuine inflammations were only considered in 6% of the examinated female patients.
