Recent advancement in the treatment of boys and adolescents with hypogonadism

Article Title: Recent advancement in the treatment of boys and adolescents with hypogonadism

Authors: Rey

Date of Publication: November 2021

“Testosterone therapy has been the standard, although off-label, in the vast majority of cases. However, more recently alternative therapies have been tested: aromatase inhibitors to induce the hypothalamic-pituitary-testicular axis in boys with constitutional delay of puberty and replacement with GnRH or gonadotrophins in those with central hypogonadism. Furthermore, follicle-stimulating hormone (FSH) priming prior to hCG or luteinizing hormone (LH) treatment seems effective to induce an enhanced testicular enlargement. Although the rationale for gonadotrophin or GnRH treatment is based on mimicking normal physiology, long-term results are still needed to assess their impact on adult fertility.”

Model for Fertility Preservation in Klinefelter Syndrome Patients

Article Title: In Vitro Propagation of XXY Undifferentiated Mouse Spermatogonia: Model for Fertility Preservation in Klinefelter Syndrome Patients

Authors: Galdon, Deebel, Zarandi, Pettenati, Kogan, Wang, Swerdloff, Atala, Lue, and Sadri-Ardekani

“These data provide the first evidence that an extra sex chromosome was lost during innate SSC culture, a crucial finding in treating KS patients for preserving and propagating SSCs for future sperm production, either in vitro or in vivo. This in vitro propagation system can be translated to clinical fertility preservation for KS patients.”

A clinical algorithm for management of fertility in adolescents with Klinefelter syndrome

Article title: A clinical algorithm for management of fertility in adolescents with the Klinefelter syndrome

Author: Masterson III, Nassaub, and Ramasamya

Date of Publication: May 2020

“In this review, we will discuss contemporary management of adolescents with Klinefelter’s syndrome, with a specific focus on fertility preservation and management of hypogonadism. As urologists often see these children after evaluation by an endocrinologist, we simplify our treatment strategy by creating case scenarios and present a treatment algorithm.”

Male infertility due to testicular disorders

Article title: Male infertility due to testicular disorders

Author: Sharma, Minhas, Dhillo, and Jayasena

Date of Publication: December 9, 2020

“Male infertility due to testicular failure has traditionally been viewed as unmodifiable. In the absence of effective pharmacological therapies, delivery of lifestyle advice is a potentially important treatment option. Future research efforts are needed to determine unidentified factors causative in ‘idiopathic’ male infertility and long-term follow-up studies of babies conceived through ART [assisted reproductive techniques].”

Infertility considerations in Klinefelter syndrome: From origin to management

Article Title: Infertility considerations in Klinefelter syndrome: From origin to management

Authors: Deebel, Bradshaw, and Sadri-Ardekani

Date of Publication: December 15, 2020

“Klinefelter syndrome (KS) is defined as the presence of one or more extra “X” chromosome in a male patient. It affects approximately    1 in 600 newborn males and the most common chromosomal abnormality, leading to male hypogonadism and infertility. There is a lack of data supporting best practices for KS patients’ care. In this paper we review controversial issues in KS research ranging from mechanisms of variation in KS phenotype to abnormalities resulting in reduced sperm production to successful sperm retrieval disparities after testicular sperm extraction (TESE). Translation to live birth and offspring health is also examined. Finally, medical therapies used to optimize the hormonal status and chances of fertility in KS patients are reviewed. We will also discuss the experimental spermatogonial stem cell (SSC) treatments, which are considered the future for TESE negative patients.”

Fertility management of Klinefelter syndrome

Article Title: Fertility management of Klinefelter syndrome

Authors: Fainberg, Hayden and Schlegel

Date of Publication: October 7, 2019

“Individuals with KS have a relatively good prognosis for sperm recovery compared to other men with idiopathic NOA. Surgical success is heavily dependent upon surgical technique and the experience of the andrology/embryology team tasked with the identification and use of testicular sperm.”
