    Notes: Summary Catecholestrogens, 2-methoxyestrogens and “classical” estrogens (estrone, estradiol, estriol) were measured simultaneously in urine samples of healthy women during the menstrual cycle. All estrogen values reach a preovulatory maximum at the time of the LH peak and show a marked increase during the luteal phase as compared to the follicular phase. Catecholestrogens and estrone seem to behave similarly supporting the assumption that catecholestrogens are predominantly metabolites of estrone. Daily measurements of urinary estrogens show large interindividual variations of 2- and 4-hydroxyestrogens as well as very differing 2-hydroxy-/2-methoxyestrogen ratios. The results obtained support the assumption, that catecholestrogens and their methylethers are excretory products with no additional regulatory functions.

    Notes: Abstract 650 couples with idiopathic subfertility (mean duration: 5.7 year, range 2–21 years) were treated during 2870 cycles by three assisted conception methods (each involving mild ovarian stimulation): I timed intercourse (TI), II intrauterine insemination (IUI), III in vitro fertilization/embryo transfer (IVF/ET). Treatment started with TI in most cases and then changed to IUI after three to six cycles. Couples who failed to conceive were treated after another 3–9 cycles by IVF/ET. An overall cumulative pregnancy rate of 80.2% was reached after 18 treatment months. The pregnancy rates per treatment cycle were: TI 5.3%, IUI 6.9%, IVF/ET 15.8% (per oocyte retrieval)
