Embryo Transfer Catheter Contamination With Intravaginal Progesterone Preparations in a Simulated Embryo Transfer Model Impairs Mouse Embryo Development: Are There Implications for Human Embryo Transfer Technique?
Objectives:To study the effect of embryo transfer (ET) catheter contact with intravaginal progesterone preparations on mouse embryo development.Study Design:In a simulated ET model, ET catheters were...
Are there improvements in the accuracy of prediction of ectopic pregnancy (EP) in women with early symptomatic pregnancy using human chorionic gonadotrophin (hCG) curves when clinicians consider visit...
This study was aimed to compare immunohistochemical expression of estrogen receptor (ER)-α, progesterone receptor (PR), and calponin in gonadotrophin-releasing hormone agonist (GnRH-a)-sensitive and...
The objective was to investigate the ovarian response of Brahman heifers to two modified ovulation synchronisation protocols developed to increase the proportion of normal synchronous ovulations. Expe...
To evaluate the effects of surface electrical stimulation (SES) and to compare them with the effects of the intravaginal electrical stimulation (IVES) in women with stress urinary incontinence (SUI).
The purpose of this trial is to study whether addition of different doses of human chorionic gonadotropins during controlled ovarian stimulation for patients undergoing IVF will improve th...
Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation. It has been demonstrated that regulatory T cells expand during p...
Evaluation of the Luteolytic Effect of a Gonadotropin Releasing Hormone (GnRH) Agonist After the Administration of Human Chorionic Gonadotropin (hCG) in the Initial Follicular Phase a Its Influence on the Prognosis of in Vitro Fertilization Treatment
This study was designed to evaluate the ability of gonadotropin releasing hormone (GnRh) agonist to prevent the rise of progesterone during controlled ovarian stimulation for in vitro fert...
The purpose of this study is to compare the clinical outcomes of recombinant human chorionic gonadotrophin (rHCG) and urinary HCG (uHCG) in patients undergoing IVF cycles.
The rational of the study is to assess the implantation, pregnancy and live birth rates after the transfer of frozen- thawed embryos in natural cycles with spontaneous Luteinizing Hormone...
Medical and Biotech [MESH] Definitions
A non-estrogenic contraceptive which is a weak progestin with strong anti-progesterone properties. It is effective if used once a week orally or can also be used in intravaginal devices.
Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.
The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.
Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.
Compounds that interact with PROGESTERONE RECEPTORS in target tissues to bring about the effects similar to those of PROGESTERONE. Primary actions of progestins, including natural and synthetic steroids, are on the UTERUS and the MAMMARY GLAND in preparation for and in maintenance of PREGNANCY.
