Summary
Mitochondrial metabolism critically regulates spermatogonial stem cell (SSC) fate. Dysfunction in obesity-linked male infertility highlights mitochondria as therapeutic targets for restoring SSC homeostasis and fertility.
Area of Science:
- Reproductive Biology
- Mitochondrial Biology
- Metabolic Regulation
Background:
- Spermatogonial stem cells (SSCs) are crucial for continuous sperm production.
- Mitochondrial metabolism is increasingly recognized as a key factor in SSC self-renewal and differentiation.
- This review focuses on the role of mitochondrial metabolism in SSC fate and male infertility.
Purpose of the Study:
- To review how mitochondrial metabolism influences SSC fate decisions.
- To explore pathological changes in mitochondrial metabolism linked to obesity-associated male infertility.
- To identify potential therapeutic targets for these conditions.
Main Methods:
- Integration of multi-omics data, metabolic assays, and animal model findings.
- Comprehensive literature review of mitochondrial dysfunction in obesity-related infertility.
Main Results:
- Quiescent SSCs use glycolysis in hypoxic niches; differentiation involves a shift to oxidative phosphorylation (OXPHOS).
- Mitochondria act as signaling hubs integrating redox, dynamics, and epigenetic mechanisms.
- Obesity-induced mitochondrial dysfunction (excess ROS, fragmentation, impaired quality control) disrupts SSCs, causing infertility.
Conclusions:
- Maintaining mitochondrial metabolic integrity is vital for SSC function.
- Targeting mitochondrial quality control and metabolic balance offers promising therapeutic strategies for obesity-related male infertility.

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...

01:14Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
02:59Animal Mitochondrial Genetics
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
01:37Mitochondria
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
01:45Mitochondrial Membranes
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
