Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Optimal number of biopsies and impact of testicular histology on the outcome of testicular sperm extraction.

Urology journal, 2013
To determine the optimal number of biopsies in patients with non-obstructive azoospermia (NOA) who undergo testicular sperm extraction (TESE), and assess the impact of testicular histology on outcome.Seven hundred and forty-one patients with NOA who underwent TESE in our institution were enrolled in the study.

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.

A comparison of sperm parameters DNA fragmentation and telomere length in testicular versus ejaculated spermatozoa

Scientific Reports
While previous studies reported conflicting findings on DNA fragmentation in testicular versus ejaculated spermatozoa, this study aimed to perform a detailed analysis of testicular spermatozoa, evaluating sperm parameters and detailed morphology, DNA ...

A Unified Machine Learning Model for Relapse Prediction in Clinical Stage I Testicular Cancer

Andrology, EarlyView.
ABSTRACT Background Approximately one‐fourth of patients with clinical stage I testicular cancer relapse. For decades, risk stratification has been based on different tumor characteristics for seminomas and non‐seminomas. Previous studies primarily used Cox proportional‐hazards models and included only a limited number of variables.

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Fertility preservation for a 13-year-old male with relapsed osteosarcoma

Journal of Pediatric Surgery Case Reports, 2019
Many benign and malignant conditions require gonadotoxic treatment regimens that may threaten a child or adolescent's future fertility. Both males and females who have undergone gonadotoxic regimens are more likely to be infertile or have difficulty ...

Impact of Chemotherapy on Sperm Functional Characteristics in Patients With Testicular Germ Cell Tumours

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.

Second chance in fertility: a comprehensive narrative review of redo micro-TESE outcomes after initial failure

Asian Journal of Andrology
When microdissection testicular sperm extraction (micro-TESE) fails, a redo procedure may be the only option for patients who want a biological child. However, there are many gaps of knowledge surrounding the procedure, which need to be addressed to help
