    Karyotyping identified chromosomal abnormalities in 18 of 38 specifically selected patients with infertility or amenorrhea. Randomly selected controls showed no abnormalities, highlighting the value of targeted genetic testing for reproductive health.

    Area of Science:

    • Human Genetics
    • Reproductive Medicine
    • Clinical Cytogenetics

    Background:

    • Subfertility and amenorrhea can stem from underlying chromosomal abnormalities.
    • Targeted karyotyping is crucial for diagnosing specific reproductive health conditions.

    Purpose of the Study:

    • To investigate the prevalence of chromosomal abnormalities in patients with specific indications of reproductive dysfunction.
    • To compare karyotype findings between clinically selected patients and a randomly selected control group.

    Main Methods:

    • Karyotyping using banding techniques was performed on 38 selected patients and 19 control individuals.
    • Patient selection was based on clinical signs and symptoms suggestive of chromosomal abnormalities.

    Main Results:

    Related Experiment Videos

    • Chromosomal abnormalities were detected in 18 of the 38 selected patients.
    • No chromosomal abnormalities were found in the 19 randomly selected control individuals.
    • Three novel chromosomal abnormalities were identified in the affected patients.

    Conclusions:

    • Targeted karyotyping is highly effective in identifying chromosomal abnormalities in individuals with specific reproductive health concerns.
    • The study identified previously undescribed chromosomal abnormalities, expanding the known spectrum of genetic causes for infertility and amenorrhea.
