Unusual false-negative serum human chorionic gonadotropin detected by qualitative immunoassay: a case report of two Iraqi women

Journal of Medicine in Scientific Research, 2020
Human chorionic gonadotropin (hCG) is a human pregnancy hormone that plays a crucial role in the promotion, maintenance, and establishment of pregnancy. Measurement of hCG in early pregnancy is the first and most common test.

Human chorionic gonadotropin‐based clinical treatments for infertile men with non‐obstructive azoospermia

Andrology
Spermatogenesis is primarily controlled by follicle‐stimulating hormone and luteinizing hormone‐driven testosterone. Luteinizing hormone acts on the Leydig cells, stimulating steroid production, predominantly testosterone, and activating critical inter ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

Effect of punicalagin and human chorionic gonadotropin on body weight and reproductive traits in maiden rabbit does.

Veterinary and Animal Science, 2020
Little is known about the effect of punicalagin extracted from pomegranate or in combination with human chorionic gonadotropin on enhancing the productive and reproductive performance in rabbits that gestate for the first time.

Superovulation Using the Combined Administration of Inhibin Antiserum and Equine Chorionic Gonadotropin Increases the Number of Ovulated Oocytes in C57BL/6 Female Mice

PLoS ONE, 2015
Superovulation is a reproductive technique generally used to produce genetically engineered mice. Superovulation in mice involves the administration of equine chorionic gonadotropin (eCG) to promote follicle growth and then that of human chorionic ...

Variation in the Thyrotropic Activity of Human Chorionic Gonadotropin in Chinese Hamster Ovary Cells Arises from Differential Expression of the Human Thyrotropin Receptor and Microheterogeneity of the Hormone. [PDF]

, 1995
The role of hCG as a stimulator of the human thyroid has been a subject of controversy, because discrepant results have been obtained in different in vitro assays.

WFS1 Deficiency Impairs PIAS4‐Associated SUMOylation and Increases Ubiquitin‐Mediated Spermatogenesis‐Related Protein Degradation Leading to Testicular Male Infertility

Advanced Science, EarlyView.
The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.
