Living with Isochromosomy Yq
A rare chromosome difference of the Y chromosome that can affect sexual development, from delayed development to male infertility.
Understanding Isochromosomy Yq
Some people have a female appearance with delayed sexual development, streak gonads, short stature, and features like Turner syndrome. Others have a male appearance with infertility because no sperm are in the semen. Features may be noticed in the teen years or adulthood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Absent sperm in semen (azoospermia)
- Male infertility
- Smaller than usual testicles
- Enlarged male breasts (gynecomastia)
- Ambiguous genitalia
- Enlarged veins in the scrotum (varicocele)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
