Duration of luteal support (DOLS) with progesterone pessaries to improve the success rates in assisted conception: study protocol for a randomized controlled trial

Trials, 2012
Background Luteal support with progesterone is necessary for successful implantation of the embryo following egg collection and embryo transfer in an in-vitro fertilization (IVF) cycle.

Contribution to More Patient-Friendly ART Treatment: Efficacy of Continuous Low-Dose GnRH Agonist as the Only Luteal Support—Results of a Prospective, Randomized, Comparative Study

International Journal of Endocrinology, 2015
Background. The aim of this pilot study was to evaluate intranasal buserelin for luteal phase support and compare its efficacy with standard vaginal progesterone in IVF/ICSI antagonist cycles. Methods.

Vaginal use of micronized progesterone for luteal support.A randomized study comparing Utrogestan® and Crinone® 8%

Biomedical Papers, 2017
Background and Objective. Luteal phase physiology is distorted by in vitro fertilization (IVF) cycles using gonadotropin-releasing hormone (GnRH) agonists and antagonists, Controlled ovarian hyperstimulation leads to luteal phase defect and for this ...

Clinical Overview of Luteal Deficiency in Dairy Cattle

Animals, 2022
Luteal deficiency is defined as reduced progesterone (P4) steroidogenesis by the corpus luteum (CL), either in the amount or duration, or both. This work provides a clinical overview of the current understanding of luteal deficiency and its association ...

Estrous cycle-dependent changes of Fas expression in the bovine corpus luteum: influence of keratin 8/18 intermediate filaments and cytokines [PDF]

, 2012
Background Fas expression and Fas-induced apoptosis are mechanisms attributed to the selective destruction of cells of the corpus luteum (CL) during luteal regression.

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

#369 : A Case of Luteal Phase Deficiency (LPD) and Polycystic Ovarian Syndrome (PCOS). When Routine is not Enough

Fertility & Reproduction, 2023
Background and Aims: Luteal phase deficiency (LPD) is a consequence of the inability of the corpus luteum (CL) to produce an adequate level of progesterone. This manifests clinically as a short menstrual cycle and infertility.

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 ...
