Previous studies have suggested that premature luteinization (PL)during controlled ovarian stimulation (COS) decreases the implantation rate due to a negative effect on the endometrium receptivity. This study aims to describe the impact on endometrial gene expression of PL in GnRH antagonist and GnRH agonist cycles.

Premature luteinization in patients undergoing IUI can occur in up to 24% of cycles. These patients, according to recent data, have a lower pregnancy rate than controls. The possibility ...
Analyze the possible effect of the progesterone levels of the hCG administration on the oocyte embryo quality. The primary endpoint of this study is the pregnancy rate.
Elevation of serum progesterone on the day of ovulation triggering in IVF/ICSI cycles is suggested to be associated with compromized outcomes. Others found that this rise didnot affect the...
The relationship between serum progesterone level on the day of human chorionic gonadotropin administration and outcome of in vitro fertilization /intracytoplasmic sperm injection and embr...
Dopamine agonists, such as quinagolide, are able to act on the VEGFR-2 blocking antibodies, diminishing Vascular Endothelial Growth Factor effect on angiogenesis in human endometriotic les...
To determine the risk factors for Pipelle diagnostic failure, which might help health care providers to choose the appropriate protocol for endometrial evaluation individually.
In order to diagnose endometrial cancer preoperatively, outpatient endometrial biopsy with a curette is frequently performed owing to its convenience. However, in some cases, gynecologists fail to dia...
Endometrial biopsy or curetting is indicated for postmenopausal women with abnormal uterine bleeding and/or thickened endometrium. Often, endometrial biopsy or curetting yields limited benign surface ...
Background/aim: The vanishing cancer phenomenon was first reported in radical prostatectomy specimens in the absence of neo-adjuvant treatment. Reported cases are mostly well-differentiated and low-vo...
Sentinel node mapping is emerging as the alternative to lymphadenectomy in endometrial cancer. The objective of our study is to validate of the sentinel node mapping surgical algorithm and also to com...
Neoplasms of the endometrial stroma that sometimes involve the MYOMETRIUM. These tumors contain cells that may closely or remotely resemble the normal stromal cells. Endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (SARCOMA, ENDOMETRIAL STROMAL).
Formation of CORPUS LUTEUM. This process includes capillary invasion of the ruptured OVARIAN FOLLICLE, hypertrophy of the GRANULOSA CELLS and the THECA CELLS, and the production of PROGESTERONE. Luteinization is regulated by LUTEINIZING HORMONE.
A type of cardiac arrhythmia with premature contractions of the HEART VENTRICLES. It is characterized by the premature QRS complex on ECG that is of abnormal shape and great duration (generally >129 msec). It is the most common form of all cardiac arrhythmias. Premature ventricular complexes have no clinical significance except in concurrence with heart diseases.
Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.
The extension of endometrial tissue (ENDOMETRIUM) into the MYOMETRIUM. It usually occurs in women in their reproductive years and may result in a diffusely enlarged uterus with ectopic and benign endometrial glands and stroma.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
