When P4 was stratified into five groups based on nanogram per milliliter of progesterone on day 19 (10–15, 15–20, 20–30, 30–40, and >40), there was a trend downward in OPR/LBR (70, 62, 52, 50, and 33%, respectively). There was also an increase in missed abortion/...
The serum progesterone levels on the eve of the trigger day and on the day itself were significantly lower in the pregnant women (p < 0.01). We found a serum progesterone threshold of 0.9 ng/ml, as also reported by other researchers. The POI and the PFI appear to have ...
In in vitro fertilization (IVF) cycles using gonadotropin-releasing hormone agonist (GnRH-a) suppression, we investigated whether an elevated progesterone (P) level on the day of human chorionic gonadotropin (hCG) administration indicates premature luteinization and is associated with a lower pregnancy...
It was found that pregnancy rate had a significantly decreasing trend (χ2 trend in proportion = 11.6; p = 0.003) with increasing levels of serum P with no effect on fertilization and cleavage rate. Table 3. Effect of serum progesterone (P) levels on fertilization, cleavage, and pregnancy ...
Materials and Methods: In a stratified cohort study, we assigned 76 infertile women of 20-38 years old who referred to women hospital into two equal groups with fallopian tube factor infertility and PCOS. We measured the plasma levels of progesterone and estradiol on the day of HCG ...

Serum progesterone concentration on day of embryo transfer in donor oocyte cycles. J Assist Reprod Genet. 2014;31(5):569–75. Article Google Scholar Kofinas JD, Blakemore J, McCulloh DH, Grifo J. Serum progesterone levels greater than 20 ng/dl on day of embryo transfer are associated ...
ProgesteronePurposeThe purpose of this study is to investigate whether progesterone (P4) levels on the day of frozen-thawed embryo transfer (FET) to a hormonally prepared endometrium correlate with pregnancy outcomes.Methods This is a large retrospective cohort analysis comprising of N = 2010 FETs. ...
Is there a relationship between serum progesterone (P) and endometrial volume on the day of embryo transfer (ET) with ongoing pregnancy rate (OPR) in artificial endometrium preparation cycles?Patients with serum P < 9.2 ng/ml on the day of ET had a significantly lower OPR but endometrial volu...
Currently, only one progesterone assay kit (Pledge agro, FHD-AA44, China) is commercially available for the serological detection of pregnant sows 30 days post-mating. However, progesterone synthesis may be influenced by heat stress [6], potentially resulting in a heightened risk of misdiagnosis ...
