Human Semen Samples with High Antioxidant Reservoir May Exhibit Lower Post-Cryopreservation Recovery of Sperm Motility

Biomolecules, 2019
Cryopreservation-thawing of human semen was found to reduce the level of antioxidant activity surrounding the sperm, which may negatively affect post-cryopreservation (post-thaw) recovery of sperm motility.

In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

Andrology, EarlyView.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

Semen Quality in Transgender Individuals Seeking Fertility Preservation

Andrology, EarlyView.
ABSTRACT Background Transgender individuals assigned male at birth (AMAB) may choose to preserve their fertility prior to starting gender‐affirming hormone therapy (GAHT). However, limited data exist regarding the baseline reproductive and hormonal characteristics of this population before and after GAHT.

Sperm cryopreservation reduces offspring growth. [PDF]

, 2019
Sperm cryopreservation is routinely used in reproductive medicine, livestock production and wildlife management. Its effect on offspring performance is often assumed to be negligible, but this still remains to be confirmed in well-controlled within ...

Quantitative proteomic characterization of human sperm cryopreservation: using data-independent acquisition mass spectrometry

BMC Urology, 2019
Background Human sperm cryopreservation is a simple and effective approach for male fertility preservation. Methods To identify potential proteomic changes in this process, data-independent acquisition (DIA), a technology with high quantitative accuracy ...

Shorter Obstructive Intervals and Motile Sperm on Intraoperative Vasal Fluid Evaluation Predict Favorable Semen Parameters Following Vasovasostomy

Andrology, EarlyView.
ABSTRACT Background Vasectomy reversal is the primary method of fertility restoration for men who wish to pursue natural conception following vasectomy. The existing body of literature evaluating vasovasostomy (VV) success is primarily focused on endpoints that capture the presence or absence, rather than the quantity and quality, of sperm in ...

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in
