Summary
Chromosomal analysis is crucial for couples undergoing in-vitro fertilization (IVF). Many individuals seeking IVF have chromosomal aberrations, impacting fertility and necessitating karyotype evaluation.
Area of Science:
- Human Genetics
- Reproductive Medicine
- Clinical Cytogenetics
Background:
- Human fertility issues can stem from chromosomal abnormalities in either partner.
- In-vitro fertilization (IVF) necessitates understanding the role of karyotype analysis in fertility assessment.
Purpose of the Study:
- To determine the necessity of chromosomal analysis for couples undergoing IVF.
- To investigate the prevalence of chromosomal aberrations in individuals seeking IVF.
Main Methods:
- Karyotype analysis was performed on 72 couples (144 individuals) attending an IVF clinic.
- Identified chromosomal aberrations including translocations and sex chromosome mosaicism.
Main Results:
- Normal chromosomes were observed in 131 individuals.
- Chromosomal aberrations were detected in 26% (38/144) of individuals studied.
- Specific aberrations included a male carrier of Robertsonian translocation t(14q;21q), a male with reciprocal translocation t(2;4)(q14;p15), and 11 females with sex chromosome mosaicism.
Conclusions:
- Chromosomal analysis is a necessary diagnostic tool for couples seeking IVF.
- The prevalence of aberrations suggests routine karyotyping is beneficial for IVF candidates.
- Identifying chromosomal abnormalities can inform reproductive decisions and treatment strategies.
