Casper Objective: The study aimed to assess whether sub-endometrial contractility is reduced by the use of intramuscular (IM) progesterone. Design: This is a randomized clinical trial...

...Sonia Faulisi; Marco Reschini; Raffaella Borroni; Alessio Paffoni; Andrea Busnelli; Edgardo Somigliana Background: The routine assessment of day 3 serum progesterone prior to initiation of ovarian hyper-stimulation with the use of GnRH antagonists is under debate. In this study, we evaluated...

... for the statistical analysis. Serum sclerostin, free estradiol, free testosterone, and progesterone levels were measured during the menstruation, late follicular and mid-luteal phases. The unique protocol IDs were BEAH FTR-4 and NCT01418924 at ClinicalTrials.gov ID. Results: Serum sclerostin values were 1.03 ± 0.58...

...R.B. Jaffe; A.R. Midgley, Jr.; U. Goebelsmann; D.L. Snyder Serum LH, FSH and progesterone concentrations and urinary pregnanediol excretion were quantitated in 5 regularly menstruating women who received 0.5 mg chlormadinone acetate for periods ranging from 51 to 60 days. These gonadotropic hormone...

...E. Sadovsky; Y. Pfeifer; W.Z. Polishuk; F.G. Sulman Intra-amniotic injection of pregnant rat mothers with pargyline HCl (Eutonyl), a MAO blocker, produces fetal death through activation of endogenous serotonin. In the present paper 5 progesterone derivatives were tested for their capacity...

...C.J. Pauerstein; B.D. Fremming; J.E. Martin Previous investigations of the influence of exogenous progesterone on the rate of egg transport through the rabbit oviduct have yielded some conflicting data. This study was designed to measure the effects of exogenous progesterone on tubal ovum passage...

...R. Massa; L. Martini The paper presents evidence indicating that, in an “in vitro” system, progesterone may interfere with the conversion of testosterone into its “active” metabolites (5 alpha-androstan-17 beta-ol-3-one, 5 alpha-androstan-3 beta, 17 beta-diol and 5 alpha-androstan-3 alpha, 17 beta...

...G. Mikhail The secretory function of both human ovaries was studied simultaneously by comparing the concentrations of several steroids in the effluent blood from the two ovaries with their concentrations in the peripheral blood. As expected, progesterone and estradiol emerged as important secretory...

...Mary E. Carsten Purified preparations of fragmented sarcoplasmic reticulum from non-pregnant bovine uterus bind calcium from a medium containing ATP and Mg ++ . This calcium binding was enhanced in the presence of progesterone, while it is decreased in the presence of oxytocin. In the presence...

... by histochemical examination of the oviducts. These procedures failed to disrupt normal transport rates of ova as indicated by oviductal ovum recovery rates at 48 and 72 h following HCG injection. However, estrogen-induced ‘tube-locking’ of ova and progesterone-induced acceleration of ovum transport were partially...

... of the hormone on target tissues were elucidated. The origin of the name, progesterone, is given as a fine example of international cooperation in the selection of a name which has been universally accepted. The accidental discovery of the ‘Blue Color Test’ for DHIA and the development of the Allen-Correction...

...Leon Milewich; Celso Gomez-Sanchez; James D. Madden; Paul C. MacDonald 5Α-Pregnane-3,20-dione and progesterone were isolated from a pregnancy plasma pool and were identified by using a combination of chromatographic techniques and mass spectrometry. Antibodies to progesterone were obtained...

..., progesterone produced a significant inhibition of RNA synthesis in all three cell types most pronounced in the myometrium. The role of these effects is discussed with regard to the growth-inhibiting effect of gestagens in human endometrial carcinoma. © 1973 S. Karger AG, Basel 1973 Copyright / Drug Dosage...

... on the receptors for a longer period of time. Compounds U-11,555A, U-11100A, MER-25, ICI-46,474 and 66/179 produced an estrogen-like ultrastructural picture of the luminal epithelium of the rat uterus. However, when given before a standard dose of estradiol-17Β to a progesterone-treated rat, all except U-11,555A...

... with the advance in pregnancy. Hydrocortisone, progesterone, Α-fetoprotein, and trophoblast-specific antigen, were demonstrated as immune suppressive factors. From these results, it was concluded that cell-mediated immunity might be reduced in pregnant women and that this reduction might be one of the causes...

...R.W. Armstrong; S.B. Effer; E.V. YoungLai Human amniotic fluid obtained near term was examined for total progesterone, progesterone binding and total protein. Samples from patients bearing male (M) fetuses had 25.5 ± 2.0 ng/ml (n = 45) and female (F) fetuses 23.8 ± 2.7 ng/ml (n = 32). Bound...
