AI Article Synopsis

  • Traditional methods for studying sperm and embryos focused on microscopy to evaluate their structure and movement.
  • OMICS technologies, particularly transcriptomics, are now being utilized to analyze fertility markers at cellular and molecular levels with greater sensitivity.
  • This review highlights the significance of specific genes in sperm function and fertilization, and also discusses the role of shared miRNAs in sperm, oocytes, and early embryos during development.

Article Abstract

Traditionally, sperm and embryos were studied using microscopy to assess morphology and motility. However, OMICS technologies, especially transcriptomic analysis, are now being used to screen the molecular dynamics of fertility markers at cellular and molecular levels, with high sensitivity. Transcriptomics is the study of the transcriptome - RNA transcripts produced by the genome - using high-throughput methods to understand how the RNAs are expressed. In this review, we have discussed gene contributions to sperm structure and function and their role in fertilization and early embryo development. Further, we identified miRNAs shared by sperm, oocytes, and early embryos and their roles in fertilization and early embryo development.

Background: In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and motility. Primary motility of the sperm cells is acquired during their transit through the epididymis and hyperactivated motility is acquired throughout the journey in the female genital tract by a process called capacitation.

Permanent preservation of genetic resources may be indispensable for the future of humanity. This requires liquid nitrogen, as is the case for preserving animal sperm. However, this technique is expensive and poses a risk of irrecoverable sample loss on non-replenishment of liquid nitrogen in case of natural disasters.

Objectives: The Bioethics Law of August 2nd, 2021 established access to origins for people conceived by gamete donation. Two years after the implementation of this disposition, what is the proportion of former gamete donors informed about access to origins, and what is their position on this matter? What could be the potential repercussions of this new law on them? .

Methods: Retrospective single-center cohort study using questionnaires Results: When former gamete donors were asked about access to origins, only 53 % of oocytes donors and 71 % of sperm donors were aware of this measure.

Comparison of fresh testicular sperm aspiration and use of either thawed pre-frozen sperm or oocyte freezing: impact on cumulative live birth rates for couples experiencing ejaculation failure.

Study Question: Is there a difference in the cumulative live birth rate (CLBR) after fresh testicular sperm aspiration (TESA) compared with the use of either pre-frozen sperm or oocyte freezing for couples experiencing ejaculation failure on the day of oocyte retrieval?

Summary Answer: After adjusting for confounding factors, the use of pre-frozen sperm or the freezing and thawing of oocytes appeared to be as effective as TESA in achieving CLBRs for couples experiencing temporary ejaculation failure.

What Is Known Already: Male patients may be concerned about experiencing temporary ejaculation failure on the day of their partner's oocyte retrieval, in which case they may choose surgical sperm retrieval, oocyte freezing on the day, or have their sperm frozen in advance. However, the clinical efficacy of these three options has not yet been evaluated.

Excessive production of reactive oxygen species (ROS) during cryopreservation and post-thawing affects sperm quality and subsequent fertilizing capacity.
