DynPeak : An algorithm for pulse detection and frequency analysis in hormonal time series [PDF]
PLoS ONE 7, 7 (2012) e39001, 2011 The endocrine control of the reproductive function is often studied from the analysis of luteinizing hormone (LH) pulsatile secretion by the pituitary gland. Whereas measurements in the cavernous sinus cumulate anatomical and technical difficulties, LH levels can be easily assessed from jugular blood.

Steroid Hormone Content of the Gonads of the Tammar Wallaby during Sexual Differentiation1 [PDF]
Biology of Reproduction, 1992 The gonads of the tammar wallaby, Macropus eugenii, are sexually indifferent at birth (Day 0) despite the fact that phenotypic sexual differentiation has already commenced as evidenced by the presence of a scrotum in males and mammary anlagen in females.

Advanced Science, EarlyView.LRRC4 deficiency disrupts the metabolic homeostasis of mitochondrial aerobic respiration and glycolysis during GC differentiation by inhibiting the ubiquitination‐mediated degradation of YAP, which ultimately leads to POI. These findings reveal the novel molecular etiology of POI and provide a promising target for prevention and treatment.

Characterization of atrazine-induced gonadal malformations in African clawed frogs (Xenopus laevis) and comparisons with effects of an androgen antagonist (cyproterone acetate) and exogenous estrogen (17beta-estradiol): Support for the demasculinization/feminization hypothesis. [PDF]
, 2006 Atrazine is a potent endocrine disruptor that both chemically castrates and feminizes male amphibians. It depletes androgens in adult frogs and reduces androgen-dependent growth of the larynx in developing male larvae.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT This study aims to elucidate the role of the ZSWIM7 gene in the etiology of infertility, focusing on its potential association with premature ovarian insufficiency and azoospermia. We investigated an 18‐year‐old female patient who presented with primary amenorrhea, hypoplasia of the uterus and ovaries, Tanner stage II breast and pubic hair ...
