Summary
Oocyte aneuploidy, or abnormal chromosome number, increases with age and in young women with reproductive issues. Follicle-stimulating hormone (FSH) may disrupt meiosis, contributing to aneuploidy.
Area of Science:
- Reproductive biology
- Genetics
- Cell biology
Background:
- Oocyte aneuploidy incidence rises with maternal age.
- Increased aneuploidy is observed in young women with recurrent miscarriage, aneuploidy, or implantation failure.
- Follicle-stimulating hormone (FSH) is implicated in oocyte aneuploidy.
Purpose of the Study:
- To explore the role of FSH in oocyte aneuploidy.
- To investigate potential causes of aneuploidy in young women.
Main Methods:
- Review of existing literature on oocyte aneuploidy and FSH.
- Analysis of data from mouse models and human observations.
- Consideration of genetic and environmental factors.
Main Results:
- Evidence suggests FSH, both endogenous and exogenous, can induce meiotic disruption leading to aneuploidy.
- FSH may explain age-related aneuploidy, but its role in young women requires further investigation.
- Environmental contaminants and gene defects affecting meiotic gene expression are potential contributors.
Conclusions:
- FSH is a likely factor in oocyte aneuploidy, particularly in age-related cases.
- Further research is needed to understand FSH's role and other contributing factors in young women.
- Abnormalities in meiotic processes, influenced by genetics and environment, can impact oocyte quality and lead to aneuploidy.

01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
02:07Oogenesis
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...
01:22Oogenesis
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...

02:02Meiosis II
Meiosis II entails cell division and segregation of the sister chromatids, resulting in the production of four unique haploid gametes. The steps for meiosis II are similar to mitosis, except that meiosis II occurs in haploid cells, whereas mitosis occurs in diploid cells.
The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...

01:57Meiosis II
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each containing...
