Abstract

Insights

Ureaplasma urealyticum (Uu) infection reduces sulfogalactosylglycerolipid (SGG) on sperm. This blockage of SGG may contribute to male infertility.

Area of Science:

  • Reproductive biology
  • Microbiology
  • Immunology

Context:

  • Ureaplasma urealyticum (Uu) is a common cause of genitourinary infections.
  • Male infertility is a significant health concern.
  • Sperm-egg binding molecules play a crucial role in fertilization.

Purpose:

  • To investigate the effect of Ureaplasma urealyticum (Uu) infection on sulfogalactosylglycerolipid (SGG), a key molecule in sperm-egg binding.
  • To explore the potential role of SGG as a receptor for Uu on sperm.

Summary:

  • Sulfogalactosylglycerolipid (SGG) was localized to the head plasma membrane of mouse epididymal sperm.
  • SGG-positive sperm rates decreased significantly when coincubated with Uu suspension (39.0%) compared to Uu medium (82.0%).
  • Ureaplasma urealyticum (Uu) can adhere to sperm surfaces, potentially by interacting with SGG.

Impact:

  • Ureaplasma urealyticum (Uu) infection may impair male fertility by reducing SGG on sperm.
  • SGG blockage by Uu could be a molecular mechanism underlying Uu-induced male infertility.
  • Findings contribute to understanding the pathogenesis of Uu infections in the male reproductive tract.

Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...

Microbiota of the Urogenital Tract

The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
Fertilization01:38

Fertilization

During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
Yeast Signaling01:28

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
