Overview of the Gender Scan (16-40 weeks)
The Gender Scan is a pregnancy ultrasound available from 16 to 40 weeks for parents who would like an ultrasound-based assessment of their baby's sex.
By around 16 weeks, external genital anatomy can often be visualised sufficiently for an experienced ultrasound professional to give an opinion on fetal sex.
However, ultrasound-based sex determination is not guaranteed to be 100% accurate.
Fetal position, gestational age, movement and image quality can occasionally prevent a confident assessment.
The scan can also confirm fetal heartbeat and provide a limited visual check of the pregnancy at the time of the examination.
It is not an anomaly scan and should not be regarded as a comprehensive assessment of fetal anatomy.
Likewise, ultrasound assessment of genital appearance is different from genetic or chromosomal sex testing.
Routine antenatal screening and maternity care should continue as normal.
The service is performed as a home visit only.
What Does the Gender Scan (16-40 weeks) Assess?
The examination focuses primarily on ultrasound assessment of fetal sex where anatomy is clearly visible.
External genital appearance
Assesses visible fetal genital anatomy to provide an opinion on fetal sex where the baby's position allows.
Fetal position
Determines whether the baby is positioned favourably for visualisation.
Fetal heartbeat
Confirms visible cardiac activity at the time of scanning.
Fetal movement
Visible movement can be observed during the examination.
General visual assessment
Provides a limited ultrasound view appropriate to the purpose of the scan.
Who May Benefit From the Gender Scan (16-40 weeks)?
Parents who would like to know their baby's sex from 16 weeks - External genital anatomy is often visible from this stage.
People who could not determine fetal sex at an earlier scan - A later ultrasound may provide a clearer view.
People wanting a private scan in the comfort of home - The service is performed at your address.
Parents who want a visual pregnancy experience alongside sex assessment - Ultrasound provides real-time imaging of the baby.
People who have already completed their routine clinical scans but want an additional private appointment - The scan can complement, but not replace, antenatal care.
Symptoms and Reasons to Consider the Gender Scan (16-40 weeks)
A Gender Scan is an elective pregnancy ultrasound and is not designed primarily to investigate symptoms.
Wanting to know fetal sex from approximately 16 weeks - This is the principal reason for booking.
Previous inability to visualise fetal sex - Fetal position may be more favourable at a later appointment.
Wanting an additional private pregnancy scan - The service provides real-time ultrasound imaging at home.
Wanting confirmation of fetal heartbeat during the appointment - Cardiac activity can normally be visualised.
A Gender Scan should not be booked to investigate bleeding, severe abdominal pain, reduced fetal movements or other pregnancy concerns.
Contact your maternity unit promptly if you have symptoms affecting the health of you or your baby.
How to Prepare for the Gender Scan (16-40 weeks)
The baby's position can prevent confident visualisation of genital anatomy.
A result should not be treated as genetically definitive.
What Happens During the Gender Scan (16-40 weeks)?
Is the Gender Scan (16-40 weeks) Safe?
The scan uses diagnostic ultrasound and does not involve ionising radiation.
Ultrasound has no known harmful effects when used appropriately for a clinical or diagnostic purpose by trained professionals.
The examination is non-invasive and normally painless.

The expected formal reporting turnaround is approximately 1 day.
If the fetal position prevents confident sex assessment, further imaging may be suggested.
Understanding Your Gender Scan (16-40 weeks) Results
The result is based on the visible appearance of external fetal genital anatomy.
A confident ultrasound appearance can provide a useful indication of fetal sex.
However, it remains an imaging opinion rather than genetic confirmation.
Position, crossed legs, reduced visibility and other technical factors can affect accuracy.
The scan also does not assess chromosomes or diagnose sex-chromosome conditions.
What Can the Gender Scan (16-40 weeks) Detect?
Visible fetal sex characteristics - External genital anatomy can often be identified from approximately 16 weeks.
Fetal position - The baby's position at the time of scanning can be documented.
Fetal heartbeat - Cardiac activity can be visualised.
Fetal movement - Real-time ultrasound can demonstrate visible movement.
Limitations of the Gender Scan (16-40 weeks)
Fetal sex cannot always be seen - Position can prevent adequate visualisation.
Ultrasound sex assessment is not genetically definitive - DNA-based testing answers a different question.
The scan is not an anomaly scan - Detailed structural fetal screening requires an appropriate anatomy scan.
It does not replace maternity care - Routine antenatal appointments remain necessary.
Not designed for acute symptoms - Pregnancy concerns should be assessed through the maternity pathway.
