A Robertsonian translocation occurs when two acrocentric chromosomes join together. Many carriers are healthy, but in male fertility care, it can be associated with:
- low sperm count (oligozoospermia),
- absent sperm (azoospermia),
- or increased risk of unbalanced embryos.
Why semen parameters may be affected
Chromosome pairing and segregation during sperm production can be disrupted, sometimes reducing sperm production or increasing abnormal sperm.
What evaluation looks like
- semen analysis and male factor workup
- karyotype testing
- counseling on reproductive risks and options
IVF and genetic testing
Depending on the couple’s goals and history, IVF with PGT-SR may help reduce the transfer of embryos with unbalanced chromosomal content.
FAQ
- Can men with Robertsonian translocation father healthy children? Yes—many do, but risk varies by translocation type.
- Does IVF solve male factor issues? IVF/ICSI can help overcome low sperm count, while PGT-SR addresses chromosomal risk.
CTA: If semen analysis is abnormal or there’s recurrent loss, ask about karyotype + PGT-SR planning.
