Gata4 Is Required for Formation of the Genital Ridge in Mice [PDF]

open access: yes, 2013
In mammals, both testis and ovary arise from a sexually undifferentiated precursor, the genital ridge, which first appears during mid-gestation as a thickening of the coelomic epithelium on the ventromedial surface of the mesonephros. At least four genes

Germ line control of female sex determination in zebrafish [PDF]

open access: yes, 2008
A major transition during development of the gonad is commitment from an undifferentiated “bi-potential” state to ovary or testis fate. In mammals, the oogonia of the developing ovary are known to be important for folliculogenesis.

Spreading the clinical window for diagnosing fetal-onset hypogonadism in boys [PDF]

open access: yes, 2014
In early fetal development, the testis secretes – independent of pituitary gonadotropins – androgens and anti-Müllerian hormone (AMH) that are essential for male sex differentiation. In the second half of fetal life, the hypothalamic–pituitary axis gains

AMH sérico pode predizer o risco de cancelamento de ciclo e as chances de boa resposta ovariana, independentemente da idade ou FSH [PDF]

open access: yes, 2013
In the recent years, anti-Müllerian hormone (AMH) has been shown to represent a reliable marker of the ovarian reserve. In this study, we evaluate the risk of cycle cancellation and the chances of good ovarian response to controlled hyperstimulation and ...

Genetic variants in anti-Mullerian hormone and anti-Mullerian hormone receptor genes and breast cancer risk in Caucasians and African Americans [PDF]

open access: yes, 2014
Anti-Mullerian hormone (AMH) regulates ovarian folliculogenesis by signaling via its receptors, and elevated serum AMH levels are associated with an increased risk of breast cancer. No previous studies have examined the effects of genetic variants in AMH-

Gonadotrophin stimulation for in vitro fertilization significantly alters the hormone milieu in follicular fluid: a comparative study between natural cycle IVF and conventional IVF [PDF]

open access: yes, 2017
STUDY QUESTION Is the steroid hormone profile in follicular fluid (FF) at the time of oocyte retrieval different in naturally matured follicles, as in natural cycle IVF (NC-IVF), compared with follicles stimulated with conventional gonadotrophin ...

Fertility and gonadal function in female survivors after treatment of early unfavorable Hodgkin lymphoma (HL) within the German Hodgkin Study Group HD14 trial [PDF]

open access: yes, 2017
Background In the HD14 trial, 2× BEACOPPescalated+2× ABVD (2+2) has improved the primary outcome. Compared with 4× ABVD, this benefit might be compromised by more infertility in women. Therefore, we analyzed gonadal function and fertility.

Utilidad de la hormona anti-mülleriana (AMH) y la inhibina B en el diagnóstico del hipogonadismo en el niño [PDF]

open access: yes, 2014
Durante la infancia, el eje hipotálamo-hipófiso-testicular se encuentra parcialmente quiescente: bajan los niveles de gonadotrofinas y la secreción de testosterona disminuye siguiendo a la caída de la LH.
