Linking socio-sexual and vocal behaviour with faecal progesterone and oestrogen metabolite levels in Southern white rhinoceros females.

Conservation physiology

Jenikejew J, Wauters J, Dehnhard M, Scheumann M.
PMID: 34987828
Conserv Physiol. 2021 Dec 29;9(1):coab098. doi: 10.1093/conphys/coab098. eCollection 2021.

Progesterone and oestrogen are the main gonadal steroid hormones that regulate the ovarian activity and induce the fertile oestrus period in females. The monitoring of this receptive phase is particularly decisive for captive breeding and is commonly based on...

Pubertal Testosterone and the Structure of the Cerebral Cortex in Young Men.

Cerebral cortex (New York, N.Y. : 1991)

Liao Z, Patel Y, Khairullah A, Parker N, Paus T.
PMID: 33429422
Cereb Cortex. 2021 May 10;31(6):2812-2821. doi: 10.1093/cercor/bhaa389.

Adolescence is a period of brain maturation that may involve a second wave of organizational effects of sex steroids on the brain. Rodent studies suggest that, overall, organizational effects of gonadal steroid hormones decrease from the prenatal/perinatal period to...

Co-treatment of testosterone and estrogen mitigates heat-induced testicular dysfunctions in a rat model.

The Journal of steroid biochemistry and molecular biology

Jeremy M, Gurusubramanian G, Roy VK, Kharwar RK.
PMID: 34688845
J Steroid Biochem Mol Biol. 2021 Nov;214:106011. doi: 10.1016/j.jsbmb.2021.106011. Epub 2021 Oct 21.

The two gonadal steroid hormones, testosterone and estrogen, regulate spermatogenesis by proliferation, differentiation, and apoptosis of testicular cells. It has been reported that heat stress or increased scrotal temperature impairs spermatogenesis in many mammals. Moreover, testicular heat stress has...

The infectious respiratory disease coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) shows striking differences in its course and severity depending on the gender of affected patients. The incidence in women is...

Characteristics of the vaginal microbiome in women with premature ovarian insufficiency.

Journal of ovarian research

Wu J, Ning Y, Tan L, Chen Y, Huang X, Zhuo Y.
PMID: 34879874
J Ovarian Res. 2021 Dec 08;14(1):172. doi: 10.1186/s13048-021-00923-9.

PURPOSE: To investigate the relationship between vaginal microbial community structure and premature ovarian insufficiency (POI).METHODS: Twenty-eight women with POI and 12 healthy women were recruited at Shenzhen Maternity and Child Healthcare Hospital between August and September 2020. Blood samples...

Kallmann syndrome and ichthyosis: a case of contiguous gene deletion syndrome.

Endocrinology, diabetes & metabolism case reports

Berges-Raso I, Giménez-Palop O, Gabau E, Capel I, Caixàs A, Rigla M.

Endocrinol Diabetes Metab Case Rep. 2017 Sep 28;2017. doi: 10.1530/EDM-17-0083. Epub 2017 Sep 28.

Kallmann syndrome is a genetically heterogeneous form of hypogonadotropic hypogonadism caused by gonadotropin-releasing hormone deficiency and characterized by anosmia or hyposmia due to hypoplasia of the olfactory bulbs; osteoporosis and metabolic syndrome can develop due to longstanding untreated hypogonadism....

Preparation of Molecularly Imprinted Microspheres as Biomimetic Recognition Material for In Situ Adsorption and Selective Chemiluminescence Determination of Bisphenol A.

Polymers

Xiong Y, Wang Q, Duan M, Xu J, Chen J, Fang S.
PMID: 30960705
Polymers (Basel). 2018 Jul 16;10(7). doi: 10.3390/polym10070780.

Bisphenol A (BPA) is an endocrine disrupter in environments which can induce abnormal differentiation of reproductive organs by interfering with the action of endogenous gonadal steroid hormones. In this work, the bisphenol A (BPA) molecularly-imprinted microspheres (MIMS) were prepared...

CONTEXT: Although etiopathogenesis of frontal fibrosing alopecia (FFA) is not fully discovered, it seems that hormonal factors play a role.AIMS: The aim of this study was to investigate the serum level of sex hormones in patients with FFA compared...

Effects of human chorionic gonadotrophin and castration on plasma gonadal steroid hormones of the dog.

The Canadian veterinary journal = La revue veterinaire canadienne

Post K.
PMID: 17422124
Can Vet J. 1982 Mar;23(3):98-101.

An intramuscular injection of 500 I.U. of human chorionic gonadotrophin resulted in an increase of plasma testosterone and progesterone concentrations in the intact male dog, but had no effect on plasma 17B-estradiol concentration. Castration caused a rapid decrease in...

Effect of Menstrual Cycle Phases on Plasma Lipid and Lipoprotein Levels in Regularly Menstruating Women.

Journal of clinical and diagnostic research : JCDR
