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 ...

Cryopreservation enhances vacuolization in human spermatozoa

Asian Pacific Journal of Reproduction, 2017
Objective: To evaluate the impact of freezing–thawing on the human sperm head vacuoles and the potential value of motile sperm organelle morphology examination for selection of frozen-thaw spermatozoa.Methods: In 30 sperm samples from infertile men ...

Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

Influence of sperm cryopreservation on sperm motility and proAKAP4 concentration in mice

, 2022
The protein proAKAP4 is crucial for sperm motility and has been suggested as an indicator of male fertility. We determined the relationship between proAKAP4 concentration and sperm motility parameters in mice, and investigated the effects of ...

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

Andrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Cryopreservation Induces Acetylation of Metabolism-Related Proteins in Boar Sperm

, 2023
Cryodamage affects the normal physiological functions and survivability of boar sperm during cryopreservation. Lysine acetylation is thought to be an important regulatory mechanism in sperm functions.

Prevalence of Spermatozoa in the Ejaculate of Adolescents With Klinefelter Syndrome: Implications for Fertility Counseling

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is the most common genetic cause of male infertility and is associated with nonobstructive azoospermia. Advances in surgical sperm retrieval techniques have enabled biological fatherhood in a subset of men with KS.

Changes in Semen Volume Following Vasectomy: A Retrospective Case–Control Analysis

Andrology, EarlyView.
ABSTRACT Background Vasectomy is the most common non‐diagnostic procedure performed by urologists and the only permanent form of sterilization routinely offered to men. Though vasal fluid has been estimated to represent less than 10% of seminal volume, studies describing the effect of vasectomy on semen volume remain limited.

Cryopreservation and sperm DNA integrity

, 2006
Cryopreservation of sperm is an extremely important issue in the field of male infertility as freezing can have detrimental effects on a variety of sperm functions, some of them not accessible to the traditional semen quality analysis.

Effect of Three Semen Extenders on Sperm Quality and In Vitro Fertilization Rates of Fresh and Cryopreserved Sperm Collected from Llama (Lama glama) Vas Deferens

Animals
The advances in Assisted Reproductive Technologies (ARTs) applied in South American camelid species are still scarce. The aim of this study was to compare the effects of three semen extenders, before and after the cryopreservation of spermatozoa obtained
