The mechanism of action of levonorgestrel (LNG) and mifepristone (MIF) in emergency contraception (EC), is still not fully known. The purpose of this study was to evaluate the effect of preovulatory treatment with LNG and MIF on luteal function in mo

A dedicated External Quality Assessment (EQA) system for immunoassays of reproductive hormones (LH, FSH, prolactin, hCG, progesterone, estradiol, testosterone) and cortisol was developed. This catered for the needs of a group of laboratories conducti

Ligand binding will remain the basic technique for receptor determinations in many laboratories. It can easily be set up and it is inexpensive. It has, however, the disadvantage of requiring relatively large amounts of tissue or cultured cells, if th

Twelve female volunteers from Berlin and 9 from Stockholm, all using a contraceptive pill (30 micrograms ethinyl estradiol and 150 micrograms levonorgestrel), received an intramuscular injection of estriol (E3; 1 mg in oil) on day 5 of withdrawal ble

This review deals with the methods of identifying genes that have been activated by inner or outer impulses. The activation and subsequent expression of a gene can be detected by its transcription into a corresponding messenger ribonucleic acid (mRNA

A radioimmunoassay method developed previously for the measurement of unconjugated pregnenolone, dehydroepiandrosterone, androstenedione, testosterone, dihydrotestosterone and oestradiol in peripheral plasma was applied to the assay of these steroids

Eleven unconjugated steroids were measured daily during a complete cycle in the peripheral plasma of 6 normally menstruating baboons (Papio hamadryas) by means of a radioimmunoassay procedure and the levels were compared with those found previously i

We tested the accuracy of radioimmunoassays for two hormones, progesterone and estradiol, in relation to the use of two different antisera in each assay and to the degree of purification from plasma before the assay was done. Each analyte was assayed

The likelihood of erroneous results is very high when a single dose of ligand (e.g. dihydrotestosterone) is employed in the assay of sex hormone binding globulin (SHBG) using precipitation with ammonium sulfate. However, correct results will be obtai

A method is described for assessing radiochemical purity of compounds measured by radioimmunoassay. This method is applicable in cases when chromatography is used prior to the radioimmunoassay proper. In individual fractions of the chromatographic zo
