The Sexing Scan is performed from 16 weeks of pregnancy. This ultrasound scan is for parents to be who would like to know the sex of their baby earlier than the 20 week anomaly scan offered by the NHS, or if the NHS Sonographer was unable to confirm the sex of your baby during your 20 week anomaly scan. Our sonographers are very accurate (over 99%). If we have any doubt we will invite you for a repeat sexing scan at no extra cost.

What is currently offered by the NHS?

Many NHS hospitals will offer to tell you the sex of your baby at the 20 week Anomaly scan. If the baby is not in a favourable position during your routine hospital pregnancy scan, the NHS Sonographer may not be able to see. If the sonographer could not reveal the gender of your baby during your 20 weeks anomaly scan, you will not routinely be offered another opportunity within your NHS care.

We offer the sexing scan from 16 weeks, which is earlier than the 20 week anomaly scan. We can also reveal or confirm your baby’s gender if your NHS scan did not determine if you are having a boy or a girl, with longer appointments as routine.

When can I have the Sexing Scan?

A Sexing or Gender scan can be performed from 16 weeks of pregnancy onwards. An early fetal anatomy scan will be performed by our Specialist Sonographers as routine. You will be able to see your baby's heartbeat and movements before you can feel them.

Our Sonographer will assess baby's head, brain, face, heart, stomach, kidneys, bladder, hands, feet, spine, and abdominal wall within the limits of your pregnancy gestation. How many weeks pregnant you are determines how much of baby's anatomy the sonographer can check at this stage. Other pregnancy related structures such as amniotic fluid and the position of the placenta will also be assessed. 

Due to the limitations of ultrasound, earlier sexing scans can be less successful for pregnant ladies with a higher BMI, therefore it may be best to wait a couple more weeks until baby is more developed.

How is the Sexing Scan performed?

  • Sexing ultrasound scans are usually performed ‘transabdominally’ which means over the tummy.

Patient Information

Some early pregnancy ultrasound scans are performed using a transvaginal probe technique. This technique is used to view the pelvic anatomy optimally, as the ultrasound probe can transmit safe ultrasound waves more directly to the pelvic area. In later stages of pregnancy, it may be advised to perform a transvaginal ultrasound scan to have a closer look at a baby’s anatomy, or to assess the maternal cervix.

There is no clinical risk associated with performing a transvaginal ultrasound scan. Transvaginal ultrasound scans can safely be performed during episodes of vaginal bleeding. 

It is important that you understand the procedure that is associated with this examination.

The ultrasound transducer will be placed in the vagina (the probe is prepared using high grade medical disinfectant)
The transducer will be introduced with a non latex type covering and sterile ultrasound gel.
It will be necessary to move the transducer from side to side, up and down and may be swivelled to obtain ultrasound images of your pelvic anatomy.
If you prefer, you may insert the transducer yourself, otherwise the person conducting the examination will do this.
A third person may be present during the examination acting as a chaperone, if required by the sonographer or yourself.
You may request the examination to be stopped at any time during the procedure.   

Transvaginal Ultrasound Consent

Below is a link to our Transvaginal Ultrasound Consent Form. This must be completed ahead of your appointment to confirm whether you consent or do not consent to having your scan performed internally.

Transvaginal Ultrasound Consent Form 


If you are a virgin (Virgo intacta; hymen intact), guidance determines that transvaginal ultrasound scans are clinically contraindicated. If you have discussed this concern with your referrer and wish to proceed with a transvaginal ultrasound scan, this type of examination can be performed.

Should I get the COVID-19 Vaccine in pregnancy?

COVID-19 vaccines are strongly recommended in pregnancy. Vaccination is the best way to protect against the known risks of COVID-19 in pregnancy for both women and babies. Women may wish to discuss the benefits and risks of having the vaccine with their healthcare professional and reach a joint decision based on individual circumstances.

Frequent questions regarding the COVID-19 Vaccine
