Objective. To test if serum hCG levels the morning after the ovulatory hCG injection correlate with (1) retrieval efficiency, (2) oocyte maturity, (3) embryo quality, (4) pregnancy, and/or (5) time to implantation in patients undergoing in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). Design. Retrospective cohort analysis. Setting. University-based IVF clinic. Patient(...

The functional consequences of luteinizing hormone/human chorionic gonadotropin signaling via neuronal luteinizing hormone/human chorionic gonadotropin receptors expressed throughout the brain remain unclear. A primary function of luteinizing hormone (LH) in the gonads is the stimulation of sex steroid production. As LH can cross the blood-brain barrier, present in cerebrospinal fluid and is ex...

Background: Intramural pregnancy (IMP) is a special type of ectopic pregnancy. The cause the disorder nor uniform effective treatment plan, either pharmacological or surgical treatment, has been reported. Pharmacological treatments have associated with poor clinical outcomes and higher risk bleeding during treatment. Laparoscopic surgery for intramural reported timely diagnosis early by laparos...

A 26-year-old woman at 7 weeks and 4 days of gestation presented with atypical vaginal bleeding mild abdominal pain. Transvaginal ultrasound revealed a free hypoechoic area 10 mm in the pouch Douglas 13-mm thick homogenous endometrium no evidence gestational sac. mass (46 × 38 mm) was detected outside uterine fundus. T1-weighted MRI performed, revealing 4-cm between left side fundus ovary. Labo...

( Obstet Gynecol . 2021;137:355–370) Gestational trophoblastic disease (GTD) refers to rare processes originating from the placenta that require timely and appropriate management. GTD includes partial or complete hydatidiform moles (HM), as well severe gestational neoplasia (GTN) related tumors. Obstetrician-gynecologists are more likely be involved in care of women with HM who have unclear dia...

BACKGROUND Luteinizing hormone (LH) activity in human menopausal gonadotropin (hMG) preparations is derived from human chorionic gonadotropin (hCG) rather than LH. Therefore, we aimed to determine whether there are similarities in the endocrine and follicular profiles of serum and follicular fluid from controlled ovarian stimulation with the recombinant gonadotropins follicle-stimulating hormon...

We analyse data from a study involving 173 pregnant women. The data are observed values of the β human chorionic gonadotropin hormone measured during the first 80 days of gestational age, including from one up to six longitudinal responses for each woman. The main objective in this study is to predict normal versus abnormal pregnancy outcomes from data that are available at the early stages of ...
