Progesterone and the Luteal Phase

Obstetrics and Gynecology Clinics of North America, 2015
Progesterone production from the corpus luteum is critical for natural reproduction. Progesterone supplementation seems to be an important aspect of any assisted reproductive technology treatment. Luteal phase deficiency in natural cycles is a plausible cause of infertility and pregnancy loss, though there is no adequate diagnostic test.

Luteal blood flow in patients undergoing GnRH agonist long protocol

Journal of Ovarian Research, 2011
Background Blood flow in the corpus luteum (CL) is closely related to luteal function. It is unclear how luteal blood flow is regulated. Standardized ovarian-stimulation protocol with a gonadotropin-releasing hormone agonist (GnRHa long protocol) causes ...

Altered visual cortex excitability in premenstrual dysphoric disorder: Evidence from magnetoencephalographic gamma oscillations and perceptual suppression.

PLoS ONE, 2022
Premenstrual dysphoric disorder (PMDD) is a psychiatric condition characterized by extreme mood shifts during the luteal phase of the menstrual cycle (MC) due to abnormal sensitivity to neurosteroids and unbalanced neural excitation/inhibition (E/I ...

Exploring the Effects of 3D Gaze Stimulation and Color Performance in Augmented Reality‐Based Steady‐State Visual Evoked Potential

Advanced Intelligent Systems, EarlyView.
This study investigates how gaze mode and stimulus brightness affect augmented reality‐based steady‐state visual evoked potentials (AR‐SSVEP) brain‐computer interface (BCI) performance. Experiments with 20 participants show that binocular gaze improves recognition accuracy and stimulus luminance impacts performance.

Within‐Person Changes in Daily Ovarian Hormone Levels Influence Genetic Effects on Emotional Eating in Women

International Journal of Eating Disorders, EarlyView.
ABSTRACT Introduction Ovarian hormones (i.e., estradiol, progesterone) show robust phenotypic associations with binge eating and related behaviors (e.g., emotional eating) in females. Recent research suggests these associations may be due to ovarian hormone effects on genetic and environmental influences on dysregulated eating. However, no research has

Apoptosis is increased and cell proliferation is decreased in out-of-phase endometria from infertile and recurrent abortion patients

Reproductive Biology and Endocrinology, 2010
Background Various endometrial abnormalities have been associated with luteal phase deficiency: a significant dyssynchrony in the maturation of the glandular epithelium and the stroma and a prevalence of out-of-phase endometrial biopsy specimens.

Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Luteal Phase in Assisted Reproductive Technology [PDF]

Frontiers in Reproductive Health, 2020
Luteal phase (LP) is the period of time beginning shortly after ovulation and ending either with luteolysis, shortly before menstrual bleeding, or with the establishment of pregnancy. During the LP, the corpus luteum (CL) secretes progesterone and some other hormones that are essential to prepare the uterus for implantation and further development of ...
