Summary
This review explores in vitro follicle maturation (IFM) in primates using 3D culture systems. It highlights advances in studying folliculogenesis and preserving fertility in cancer patients.
Area of Science:
- Reproductive Biology
- Developmental Biology
- Cell Biology
Background:
- Primate follicular development is complex and not fully understood.
- In vitro follicle maturation (IFM) offers fertility preservation options for cancer patients.
- Three-dimensional (3D) follicle culture systems provide a model for studying primate folliculogenesis.
Purpose of the Study:
- To review published data on in vitro follicular development in nonhuman primates.
- To explore the potential of 3D culture systems for studying primate folliculogenesis.
- To identify strategies for improving in vitro follicle maturation for fertility preservation.
Main Methods:
- Review of published literature on in vitro follicular development in nonhuman primates.
- Analysis of data on follicle survival, growth, and function in 3D culture.
- Evaluation of oocyte maturation and fertilization rates in vitro.
Main Results:
- Summarizes current knowledge on preantral to small antral stage follicular development in vitro.
- Discusses endocrine and paracrine/autocrine regulation of folliculogenesis.
- Highlights challenges and strategies for improving oocyte competence for fertilization and embryonic development.
Conclusions:
- 3D follicle culture systems are valuable for studying primate folliculogenesis.
- IFM holds promise for fertility preservation in female cancer patients.
- Further research is needed to optimize conditions for human follicle culture and clinical application.

Folliculogenesis
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...
Oogenesis
Oogenesis, the process of developing egg cells (female gametes), occurs within the ovaries and is fundamental to female fertility. This sequence begins during fetal development when diploid oogonia in the developing ovaries undergo mitotic divisions to produce primary oocytes. By birth, these primary oocytes enter prophase I of meiosis but become arrested in this stage, remaining suspended until puberty.
Each primary oocyte is surrounded by a layer of pre-granulosa cells, forming what is known...

Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
