Current Opinion in Obstetrics and Gynecology, 1994
The corpus luteum is controlled by luteinizing hormone (LH) and intraovarian morphofunctional specialization and autocrine/paracrine mechanisms. Corpus luteal insufficiency produces luteal phase defects (LPD). The poor precision and validation of endometrial histologic dating and single or random multiple serum progesterone measurements produce widely ...

Obstetrical & Gynecological Survey, 1970
ABSTRACT From among a group of women with apparently normal menstrual cycles, 7 cycles with short luteal phases were identified. These cycles were characterized by grossly normal FSH and LH patterns although the FSH/LH ratio was below normal. Mean plasma progesterone increased to less than 2 ng/ml shortly after the LH peak; thus, the peak level was ...

Individualized luteal phase support
Current Opinion in Obstetrics & Gynecology, 2019Purpose of review The aim of this review is to summarize the different aspects of luteal phase deficiency in IVF treatment and the possibilities of individualized luteal phase support. Recent findings After the application of human chorionic gonadotrophin (hCG) for final oocyte ...

Progestogens in luteal support
Hormone Molecular Biology and Clinical Investigation, 2020Abstract Progestational agents are often prescribed to increase the clinical pregnancy rate in assisted reproduction. Progestogens affect implantation, cytokine balance, natural killer cell activity, arachidonic acid release and myometrial contractility.

Fertility and Sterility, 1976
In summary, the luteal phase defect is a deficiency of corpus luteum progesterone steroidogenesis, either in amount or duration, or both. The clinical manifestations include either primary infertility or repeated first trimester abortions. The diagnosis can only be made clinically on the basis of a well-timed endometrial biopsy that is read ...

PROLACTIN AND LUTEAL INSUFFICIENCY
Clinical Endocrinology, 1978SUMMARYThe relationship between mid‐luteal plasma levels of progesterone and prolactin was studied in 75 women with regular menstrual cycles. Eighteen women had normal prolactin (mean 260 ± 51.7 mU/l) and normal progesterone levels (mean 67 ± 21.3 nmol/l).

Luteal phase after ovarian hyperstimulation
BJOG: An International Journal of Obstetrics & Gynaecology, 1987SummaryThe luteal phase was investigated in 17 women with normal menstrual cycles and tubal infertility who were superovulated with clomiphene (9 cycles), clomiphene plus pulsatile human menopausal gonadotrophin (hMG) (12 cycles) and clomiphene plus pulsatile follicle stimulating hormone (FSH) (11 cycles) during an in‐vitro fertilization programme ...

Large Luteal Cells the Source of Luteal Oxytocin in the Sheep
Obstetrical & Gynecological Survey, 1983To determine the cellular origin of oxytocin produced by the cyclical corpus luteum (CL) of the sheep, enriched fractions of enzymatically dispersed small and large luteal cells from 12 CL were prepared on a Ficoll 400 gradient. Oxytocin was measured by RIA.

Theriogenology, 2017
This study aimed to assess the luteal dynamics of pregnant and non-pregnant Saanen goats throughout an estrous cycle by B-mode and color Doppler ultrasonography (US) associated with a P4 hormonal assay. Furthermore, a cutoff point was chosen to determine the corpus luteum (CL) functionality by luteal biometry (LB) measurement and luteal blood flow (LBF)
