Distribution of GnRH and Kisspeptin Immunoreactivity in the Female Llama Hypothalamus.

Front Vet Sci 2020 2;7:597921. Epub 2021 Feb 2.

Instituto de Ciencia Animal, Facultad de Ciencias Veterinarias, Universidad Austral de Chile, Valdivia, Chile.

Llamas are induced non-reflex ovulators, which ovulate in response to the hormonal stimulus of the male protein beta-nerve growth factor (β-NGF) that is present in the seminal plasma; this response is dependent on the preovulatory gonadotrophin-releasing hormone (GnRH) release from the hypothalamus. GnRH neurones are vital for reproduction, as these provide the input that controls the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. However, in spontaneous ovulators, the activity of GnRH cells is regulated by kisspeptin neurones that relay the oestrogen signal arising from the periphery. Read More

J ASEAN Fed Endocr Soc 2020 4;35(2):215-219. Epub 2020 Nov 4.

Department of Endocrinology, Cardinal Santos Medical Center, San Juan City, Philippines.

Primary partial empty sella occurs when less than 50% of an enlarged or deformed sella turcica is filled with cerebrospinal fluid in the setting of unidentified etiologic pathological conditions. Prepubertal hypogonadotropic hypogonadism presenting as its main manifestation is rare since its peak incidence commonly occurs late at 30 to 40 years of age and has a sexual predilection for female. We described a case of 20-year-old male who presented with micropenis and absent secondary sex characteristics. Read More

Impact of Hormonal Replacement Therapy on Bone Mineral Density in Premature Ovarian Insufficiency Patients.

J Clin Med 2020 Dec 7;9(12). Epub 2020 Dec 7.

Department of Gynecological Endocrinology, Poznan University of Medical Sciences, 33 Polna Street, 60-535 Poznan, Poland.

Premature ovarian insufficiency (POI) is a type of hypergonadotropic hypogonadism caused by impaired ovarian function before the age of 40. Due to the hypoestrogenism, women with POI experience a variety of health complications, including an increased risk of bone mineral density loss and developing osteopenia and osteoporosis, which poses an important problem for public health. The aim of this study was to evaluate and compare the values of bone mineral density (BMD), T-score and Z-score within the lumbar spine (L1-L4) using the dual energy X-ray absorptiometry method.

Dept. of Aquatic Life Medical Sciences, Sunmoon University, Asan 31460, Korea.

Kisspeptin, expressed mainly in the hypothalamus, stimulates gonadotropin-releasing hormone neurons to facilitate reproduction. In some model animals, the kisspeptin is also expressed in the pituitary. Recently, a pathway has been suggested in which kisspeptin acts directly on the pituitary to secretion of gonadotropin in mammals. Read More
