Study TitleMetabolomics analysis of human spermatozoa reveals impaired metabolic pathways in asthenozoospermia (MS data)
Study SummaryBackground: Infertility is a major health issue, affecting 15% of reproductive-age couples with male factors contributing to 50% of cases. Asthenozoospermia, or low sperm motility, is a common cause of male infertility with complex etiology, involving genetic and metabolic alterations, inflammation, and oxidative stress. However, the molecular mechanisms behind low motility are unclear. In this study, we used a metabolomics approach to identify metabolic biomarkers and pathways involved in sperm motility. Methods: We compared the metabolome and lipidome of spermatozoa of men with normozoospermia (n = 44) and asthenozoospermia (n = 22) using untargeted LC-MS and the metabolome of seminal fluid using 1H-NMR. Additionally, we evaluated the seminal fluid redox status to assess the oxidative stress in the ejaculate. Results: We identified 112 metabolites and 209 lipids in spermatozoa and 27 metabolites in the seminal fluid of normozoospermic and asthenozoospermic men. PCA analysis of the spermatozoa’s metabolomics and lipidomics data showed a clear separation between groups. Spermatozoa of asthenozoospermic men presented lower levels of several amino acids, and increased levels of energetic substrates and lysophospholipids. However, the metabolome and redox status of the seminal fluid was not altered in asthenozoospermia. Conclusions: Our results indicate impaired metabolic pathways associated with redox homeostasis and amino acid, energy, and lipid metabolism in asthenozoospermia. Taken together, these findings suggest that the metabolome and lipidome of human spermatozoa are key factors influencing their motility and that oxidative stress exposure during spermatogenesis or sperm maturation may be in the etiology of decreased motility in asthenozoospermia.

Collection:

Collection ID:CO003379
Collection Summary:Human seminal samples were obtained through masturbation into a specific sterile container after 2 to 4 days of sexual abstinence. After collection, samples were left at 37°C until complete liquefaction and sperm parameters (semen pH, ejaculate volume, sperm concentration, sperm count and sperm motility) were analyzed according to the WHO guidelines 5. After routine semen analysis, spermatozoa were separated from the seminal fluid through centrifugation at 500.g for 5 min. Pelleted spermatozoa were washed two times with phosphate buffer saline (PBS) before being stored at -80°C.
Sample Type:Spermatozoa
Storage Conditions:-80℃

Treatment Summary:Participants enrolled in this study were randomly recruited among men who attended fertility consultations at the Centre for Reproductive Genetics Professor Alberto Barros (Porto, Portugal) and the Centro Hospitalar Universitário de Santo António (Porto, Portugal) from March to June 2021. Adult men (age ≥ 18 years) diagnosed with asthenozoospermia (AS, sperm total motility < 42%) were recruited for AS group and men with normal sperm parameters (sperm concentration ≥ 15 million cells/mL, sperm count ≥ 39 million cells and sperm total motility ≥ 42%) were recruited for the control group (normozoospermia (NZ) group).

Sample Preparation:

Sampleprep ID:SP003393
Sampleprep Summary:Pellets containing 20 million spermatozoa were resuspended in 500 µL of ice-cold methanol/water (4:1, v/v) solution and subjected to ultrasonic homogenization in a Vibra Cell sonicator (Sonics & Materials, Inc.) for 2.5 min at 4°C, with 5 s ON - 5 s OFF intervals with 20% amplitude using a ¼” probe. Samples were then incubated at -20°C for 30 min to allow protein precipitation, and centrifuged at 14000.g for 30 min at 4°C. After centrifugation, supernatants were collected into a new 1.5 mL centrifuge tube, dried in SpeedVac Plus SC 210A (Thermo Savant, NY, USA), and stored at -20°C before LC-MS analysis.
