Early adolescence assessment of eleven boys treated with continuous subcutaneous infusion of recombinant LH and FSH during infancy

Endocrine Connections
We previously observed that continuous subcutaneous gonadotropin infusion (CSGI) in infants with congenital hypogonadotropic hypogonadism (CHH) can mimic minipuberty.

Inducible Kiss1 knockdown in the hypothalamic arcuate nucleus suppressed pulsatile secretion of luteinizing hormone in male mice

The Journal of Reproduction and Development, 2020
Accumulating evidence suggests that kisspeptin-GPR54 signaling is indispensable for gonadotropin-releasing hormone (GnRH)/gonadotropin secretion and consequent reproductive functions in mammals. Conventional Kiss1 knockout (KO) mice and rats are reported

Use of the Abbott i‐STAT®1 point of care device for hCG quantification in early pregnancy

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objectives To evaluate the use of the Abbott i‐STAT®1 point‐of‐care‐test (POCT) device for measurement of human chorionic gonadotropin (hCG) to support the management of early pregnancy complications in a remote early pregnancy unit (EPU). Methods Women attending the EPU who required an hCG blood test were invited to take part in the study ...

Molecular Mechanisms of Gonadotropin-Releasing Hormone Signaling: Integrating Cyclic Nucleotides into the Network

Frontiers in Endocrinology, 2013
Gonadotropin-releasing hormone (GnRH) is the primary regulator of mammalian reproductive function in both males and females. It acts via G-protein coupled receptors on gonadotropes to stimulate synthesis and secretion of the gonadotropin hormones ...

Uterine “twisting sign”: A new potential ultrasonographic soft marker for deep endometriosis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The objective of the current study was to evaluate the “twisting sign,” defined as uterine fundus rotation observed on transvaginal sonography (TVS), as a potential soft marker for deep endometriosis (DE) and its association with specific DE localizations and indirect signs.

Neuroendocrine regulation of gonadotropin secretion in seasonally breeding birds

Frontiers in Neuroscience, 2013
Seasonally breeding birds detect environmental signals, such as light, temperature, food availability, and presence of mates to time reproduction. Hypothalamic neurons integrate external and internal signals, and regulate reproduction by releasing ...

Dienogest use and the risk of breast and gynecologic cancers: A nationwide population‐based study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To evaluate whether dienogest exposure is associated with the risk of breast, endometrial, or tubo‐ovarian cancer in women with endometriosis. Methods In this nationwide retrospective cohort study (January 2012 to December 2023), we used the Korean National Health Insurance Review & Assessment Service database. Women aged 20–49 years
