Twenty-six naturally cycling, healthy women were tested thrice: during menses, in the follicular phase, and in the luteal phase. In the emotional face flanker task, a significant positive relation was found between progesterone levels and reaction times (RTs) for sad faces, suggesting that high ...
When a woman’s body is constantly wound up in go, go, go mode, heradrenal glands can get overworked to the point that they no longer produce enough progesteronein relation to estrogen. Usually this is because her adrenals are instead having to produce cortisol (a “fight or flight” horm...
Endometrial receptivity is affected in women with high circulating progesterone levels at the end of the follicular phase: a functional genomics analysis. BACKGROUND Elevated serum progesterone levels at the end of the follicular phase in controlled ovarian stimulation (COS) leads to a poorer ongoing ...
High levels of prolactin, also known ashyperprolactinemia, can cause infertility in women. Periods can become irregular. If your levels are very high -- up to 1,000 times the upper limit of what’s considered normal -- this could be a sign that you have prolactinoma -- a tumor in your ...
PCOS is one of the most common endocrine disorders among women of reproductive age. While the mechanism involved is not yet fully characterized. Our study aims to examine the pregnancy outcomes of embryo transfers in women with PCOS after pretreatment, a

Methods Admitting the participants solely in the follicular phase resulted in high and low plasma-estradiol whereas plasma-progesterone was similar. Urine and blood samples were taken at predetermined time points to determine plasma AVP, plasma oxytocin, plasma aldosterone, plasma natriuretic peptide (...
The LH RF test on patients with persistently high LH levels proved 8 of them to be of high positive response, except for one. Fractionation of the blood estrogen revealed that E1 and E2 fractions tended to increase, but E3 fraction tended to decrease. No marked variations in progesterone ...
Serum concentrations of testosterone (T), progesterone, and estradiol were measured using radioimmunoassay at the Beijing North Institute of Biological Technology (Beijing, China). The levels of luteinizing hormone and follicle stimulating hormone in serum were measured with ELISA kits (Elabscience) ...
