Living with Isochromosomy Yp
A rare chromosome difference of the Y chromosome that can affect male development and fertility, from no noticeable effects to infertility.
Understanding Isochromosomy Yp
Presentations vary widely. Some males are healthy and fertile. Others are infertile, and some have ambiguous genitalia or incomplete masculinization. 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
- Reduced function of the testicles
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
