| pubmed-article:668929 | pubmed:abstractText | Prostaglandin F (PGF) was measured in endometrial samples from eight women wearing Lippes Loops and 14 women wearing Progestaserts after 6 months' use of the intrauterine devices (IUDs). In addition, in 37 women wearing dydrogesterone-T IUDs, endometrial PGF was measured after 1 month, 3 to 7 months, and 8 to 12 months of use. Endometrial samples were also obtained from 51 women without IUDs. The following means and standard errors of endometrial PGF, expressed in picograms per microgram of endometrial protein, were obtained in women without IUDs: early proliferative phase, 3.11 +/- 1.0; midproliferative phase, 4.1 +/- 0.7; late proliferative phase, 4.4 +/- 1.0; midluteal phase, 7.13 +/- 1.0; and late secretory phase, 6.08 +/- 1.0. The midproliferative phase mean was significantly different from the midsecretory phase mean (P is greater than 0.05). Except for one group, no differences were noted during the midproliferative and midsecretory phases among the groups of women wearing medicated and nonmedicated IUDs, when compared with values for women without IUDs. The only difference noted was during the midsecretory phase in the dydrogesterone group at 8 to 12 months. In these women, the mean endometrial PGF content was 2.8 +/- 0.8, significantly different (P is greater than 0.05) from that of women without IUDs (6.1 +/- 1.0). | lld:pubmed |
