Embryonic estrogen exposure recapitulates persistent ovarian transcriptional programs in a model of environmental endocrine disruption.

Biol Reprod 2019 Jan;100(1):149-161

Savannah River Ecology Laboratory, Aiken, South Carolina, USA.

Estrogens regulate key aspects of sexual determination and differentiation, and exposure to exogenous estrogens can alter ovarian development. Alligators inhabiting Lake Apopka, FL, are historically exposed to estrogenic endocrine disrupting contaminants and are characterized by a suite of reproductive abnormalities, including altered ovarian gene expression and abated transcriptional responses to follicle stimulating hormone. Here, we test the hypothesis that disrupting estrogen signaling during gonadal differentiation results in persistent alterations to ovarian gene expression that mirror alterations observed in alligators from Lake Apopka.

Key Lab of Reproduction Regulation of NPFPC, SIPPR, IRD, Fudan University, Xietu Road 2140, Xuhui District, Shanghai, 200032, China.

Background: LepR tyrosine site mutation mice (Y123F) exhibit decreased serum E2 levels, immature reproductive organs, infertility as well as metabolic abnormalities. Although the actions of leptin and lepR in the control of reproductive function are thought to be exerted mainly via the hypothalamic-pituitary-gonadal axis, relatively less is known regarding their local effects on the peripheral ovary, especially on steroid hormone synthesis. Meanwhile, whether the decreased fertility of Y123F mouse could be restored by gonadotropin has not been clear yet. Read More

J Clin Res Pediatr Endocrinol 2018 11 19;10(4):377-381. Epub 2018 Mar 19.

Dicle University Faculty of Medicine, Department of Pediatric Endocrinology, Diyarbakır, Turkey

Aromatase deficiency is a rare autosomal recessive genetic disorder with an unknown incidence. Aromatase converts androgens into estrogen in the gonadal and extra-gonadal tissues. Aromatase deficiency causes ambiguous genitalia in the female fetus and maternal virilization (hirsutism, acne, cliteromegaly, deep voice) during pregnancy due to increased concentration of androgens.

Klinefelter syndrome and fertility-Impact of X-chromosomal inheritance on spermatogenesis.

Andrologia 2018 Jun 7;50(5):e13004. Epub 2018 Mar 7.

Department of Obstetrics and Gynaecology, Radboudumc Nijmegen, Nijmegen, The Netherlands.

With the use of testicular sperm extraction (TESE), spermatozoa can be retrieved in about 30%-50% of men with Klinefelter syndrome (KS). The reason for the absence or presence of spermatozoa in half of the men with KS remains unknown. Therefore, the search for an objective marker for a positive prediction in finding spermatozoa is of significant clinical value to avoid unnecessary testicular biopsies in males with (mostly) low testicular volume and impaired testosterone.
