When elevated serum hCG is discovered during the work up of a gynecologic tumor, it is paramount to identify the source of hCG prior to initiation of treatment. Potential sources of hCG include viable intrauterine pregnancy, ectopic pregnancy, miscarriage, gestational trophoblastic disease, pituitary hCG production, phantom hCG (heterophilic antibody interference), and tumor production. Here, we present a case of elevated hCG in a young women with a large complex pelvic mass. Prior to treatment initiation, the patient underwent work up for hCG elevation, which was ultimately found to be from tumor production. Pathologic examination revealed the mass to be a mucinous adenocarcinoma of the ovary with aberrant expression of hCG, rather than the more typical hCG producing germ cell tumor. We detail the preoperative evaluation process of hCG elevation. Additionally, we discuss the role of hCG in ovarian cancer and influence on tumorigenesis and management.

Photoperiodic changes induce seasonal variations in vitamin D levels, which can affect reproductive function. The muskrat, a seasonal breeder, possesses a pair of scented glands that secrete musky substances to attract mates. The scented glands can also synthesize androgens, which regulate their function through autocrine or paracrine signaling.

Background: The effectiveness of changing the type of luteal phase support in patients with poor ovarian response (POR) remains unclear based on the available evidence. This study aimed to compare the effectiveness of various luteal phase support (LPS) methods, including progesterone alone, human chorionic gonadotropin (hCG) alone, and the combination of progesterone with hCG, in these patients.
Materials And Methods: In this randomized clinical trial, 375 patients diagnosed with POR based on the Bologna criteria underwent intracytoplasmic sperm injection-embryo transfer (ET) cycles at the Royan Institute between November 2015 and June 2019.

Introduction And Importance: Uterine arteriovenous malformations (UAVMs) are rare vascular anomalies caused by abnormal connections between uterine arteries and veins. They can lead to severe bleeding, requiring prompt and accurate diagnosis. Historically treated with hysterectomy, transcatheter vascular embolization has emerged as a fertility-sparing alternative.

Background: The majority of machine learning applications in assisted reproduction have been focused on predicting the likelihood of pregnancy. In the present study, we aim to investigate which machine learning models are most effective in predicting the occurrence of a high proportion (>30 %) of 3PN/MPN zygotes in individual IVF cycles.
Methods: Eight machine learning algorithms were trained and compared, including the AdaBoost and Gaussian NB.
