Summary
Sperm protein changes after epididymitis may impact male fertility. Proteomic analysis revealed altered protein levels, suggesting a role in post-inflammatory subfertility.
Area of Science:
- Reproductive Biology
- Proteomics
- Andrology
Background:
- Acute epididymitis can lead to male infertility.
- Conventional semen analysis may not detect all fertility issues post-epididymitis.
Purpose of the Study:
- To investigate postinflammatory alterations in sperm protein composition.
- To evaluate potential molecular factors contributing to subfertility after acute epididymitis.
Main Methods:
- Prospective case-control study involving 8 patients post-epididymitis and 10 controls.
- Sperm proteome analysis using 2D gel electrophoresis and MALDI-TOF mass spectrometry.
- Immunofluorescence staining validated protein expression changes (ATP5B, TUBA1A, TUBB4B).
Main Results:
- Identified 35 down-regulated proteins in sperm from epididymitis patients.
- Confirmed reduced expression of ATP5B, TUBA1A, and TUBB4B via immunofluorescence.
Conclusions:
- Significant alterations in sperm protein composition occur after epididymitis.
- These proteomic changes may contribute to subfertility/infertility in affected men.

01:41Spermatogenesis
91.0K
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...

01:22Spermatogenesis
8.3K
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...

01:23Infertility in Males
665
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

01:15Sperm Transport
5.5K
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.

01:22Sperm Structure and Semen Composition
16.5K
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...

The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...
