The right ovary of the 15-year-old girl is not clearly visible.

A 15-year-old girl with unclear visualization of the right ovary may be due to poor bladder retention, congenital developmental abnormalities, ovarian atrophy, or other factors. Symptomatic management should be based on specific circumstances. Detailed analysis is as follows:

1. Poor bladder retention

Unclear visualization of the right ovary in a 15-year-old girl is usually an ultrasound imaging finding. Ultrasound uses specific sound waves that reflect differently off various organs to produce images. If the patient has insufficient fluid intake or poor bladder retention during the examination, adequate imaging may not be achieved, leading to this result. It is recommended to repeat the examination after proper bladder filling.

2. Congenital developmental abnormality

If a 15-year-old girl has a congenital abnormality in ovarian development—such as an underdeveloped (small) right ovary or absence of the right ovary—this condition may also occur. If no other abnormal symptoms are present, it typically does not affect daily life and generally requires no special treatment.

3. Ovarian atrophy

If the abdomen suffers external trauma causing severe damage to the ovary, and wound hygiene is neglected during healing, resulting in infection or contamination, ovarian atrophy may develop and lead to this finding. It is recommended to seek medical evaluation at a hospital for relevant examinations and appropriate treatment.

In addition, this may also be caused by prior oophorectomy (ovary removal). Further diagnostic evaluation combined with additional tests is advised.
