Summary
SEPTIN 7 (SEPT7) protein expression is crucial for sperm function. Defective SEPT7 signals were more common in infertile men with asthenozoospermia and sperm morphological defects.
Area of Science:
- Reproductive biology
- Cell biology
- Spermatogenesis research
Background:
- SEPT7 is a protein involved in cell structure.
- Its role in sperm development and function is not fully understood.
Purpose of the Study:
- To examine SEPT7 protein expression during mouse spermiogenesis.
- To investigate SEPT7's role in human sperm function and its association with infertility.
Main Methods:
- Immunofluorescence assay (IFA) used to analyze SEPT7 expression in mouse sperm development.
- IFA applied to human ejaculated sperm from fertile controls and infertile men with asthenozoospermia.
- Assessment of SEPT7 signal frequency in relation to sperm morphology.
Main Results:
- SEPT7 expression patterns observed during mouse spermiogenesis.
- A higher frequency of defective SEPT7 signals found in infertile men with asthenozoospermia.
- Absence of SEPT7 signal correlated with increased sperm morphological abnormalities.
Conclusions:
- SEPT7 protein likely regulates subcellular structure formation during mouse spermiogenesis.
- SEPT7 deficiency is associated with multiple defects in human sperm.
- SEPT7 may serve as a biomarker for sperm quality and male fertility.

01:19Septins
Septins are protein filaments forming the cytoskeleton along with the microtubules, microfilaments, intermediate filaments, and other accessory proteins. In 1971 while studying the cell division cycle in mutant Saccharomyces cerevisiae Harwell et al. first identified the septin-related genes playing a crucial role in yeast cytokinesis. Fluorescence microscopy revealed that these proteins localize at the budding neck as rings. These ring-like proteins were then named Septins by John Pringle, and...
01:02Role of Septins
Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.

01:22Sperm Structure and Semen Composition
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...
01:41Spermatogenesis
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...
01:22Spermatogenesis
Spermatogenesis is a complex process that involves the development of sperm cells from undifferentiated stem cells in the seminiferous tubules of the testes. The process is essential for the production of mature and functional sperm cells that are capable of fertilizing an egg.
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

01:15Sperm Transport
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
