Article Synopsis
  • * A comprehensive review of 68 articles highlights the necessity of tailored care and preventive measures for transmasculine individuals, emphasizing that they don't have an increased cancer risk linked to hormonal therapy.
  • * The study underscores the importance of training healthcare professionals to meet the unique needs of transmasculine patients, ensuring appropriate follow-up and care that aligns with each individual’s experiences and transitions.

Purpose: Progress has been made in understanding trans health needs, but research priorities are often set by policy or healthcare professionals without trans input, which may not reflect public needs. Our study sought to identify trans health research priorities in France from both researchers and the trans community.

Methods: Expert stakeholders (health and social sciences professionals, trans individuals, and their families) answered a three-round Delphi survey on trans health research priorities.

Article Synopsis
  • The study investigates whether testicular sperm extraction (TESE) should be done after puberty or delayed until adulthood in patients with non-mosaic 47,XXY Klinefelter syndrome (KS).
  • Results show no significant difference in sperm retrieval rate (SRR) between younger patients (ages 15-22) and older patients (ages 23-43), with overall SRR at 45.4%.
  • Key hormonal factors like Anti-Müllerian hormone (AMH) and inhibin B were found to be higher in the younger group and in patients who successfully retrieved sperm.

Article Synopsis
  • * Research indicates that age is a significant factor in the success of TESE, with older patients (over 30) generally having lower sperm retrieval rates, while those younger than 20 show better outcomes similar to the 20-30 age range.
  • * There is still a need for more studies to explore new markers to predict sperm retrieval success, especially considering the effects of age and androgen therapy, which has shown no clear impact on retrieval outcomes.

Background: Androgens are well known to be necessary for spermatogenesis. The purpose of this study was to determine Sertoli cell responsiveness to androgens according to age from birth to puberty.

Results: Testicular tissue samples were studied in a population of 84 control boys classified into seven groups according to age: group 1 (1-30 days), group 2 (1-3 months), group 3 (3-6 months), group 4 (0.

We conducted a retrospective study on the long-term effect of mitotane treatment on testicular adrenal rest tumors (TARTs) in five adult patients with classic 21-hydroxylase deficiency. After 60 months of mitotane treatment, a decrease in adrenal steroids was observed in four patients. Testicular ultrasonography showed complete disappearance of TART in two patients, stabilization in two patients and a halving of TART volume in the remaining patient.

Rationale: Pituitary adenomas and paragangliomas are both rare endocrine diseases. Paragangliomas (PGL)/pheochromocytomas (PHEO) are part of an inherited syndrome in about 30% to 40% of cases. Among familial cases, mutations of the succinate dehydrogenase (SDH) subunit genes (succinate dehydrogenase subunit [SDH]B, SDHC, SDHD, succinate dehydrogenase subunit AF2 [SDHAF2] , and SDHA) are the most common cause.

Acromegaly is mainly due to the somatotroph pituitary neuroendocrine tumors (PitNET)s. These have been subtyped into densely granulated (DG) and sparsely granulated (SG) tumors, which differ in clinical, histological and biological characteristics and in response to somatostatin analogs (SA)s. The variable remission rate after surgical resection, as first line treatment, has increased interest in identifying pathological markers to better predict the response to medical treatment.

Background: Silent somatotroph tumours are growth hormone (GH) immunoreactive (IR) pituitary tumours without clinical and biological signs of acromegaly. Their better characterisation is required to improve the diagnosis.

Materials And Methods: Twenty-one silent somatotroph tumours were compared to 59 somatotroph tumours with acromegaly.

GH-secreting pituitary adenomas can be hypo-, iso- or hyper-intense on T2-weighted MRI sequences. We conducted the current multicenter study in a large population of patients with acromegaly to analyze the relationship between T2-weighted signal intensity on diagnostic MRI and hormonal and tumoral responses to somatostatin analogs (SSA) as primary monotherapy. Acromegaly patients receiving primary SSA for at least 3 months were included in the study.

Cardiovascular impairments are frequent in Cushing's syndrome and the hypercortisolism can result in cardiac structural and functional changes that lead in rare cases to dilated cardiomyopathy (DCM). Such cardiac impairment may be reversible in response to a eucortisolaemic state.A 43-year-old man with a medical past of hypertension and history of smoking presented to the emergency department with global heart failure.
