Can You Choose Your Baby's Sex Through IVF?
Sex selection through IVF is technically possible using PGT-SD (Preimplantation Genetic Testing for Sex Determination). Whether it is legal depends entirely on your country. In India it is a criminal offence under the PCPNDT Act 1994. In the USA it is legal. Most countries fall between these positions.
How Sex Selection Works
- Standard IVF stimulation and blastocyst development
- Trophectoderm biopsy (5-10 cells from each blastocyst at Day 5-6)
- Next-Generation Sequencing (NGS) identifies sex chromosomes: XX (female) or XY (male)
- Only embryos of the desired sex are transferred
Accuracy: greater than 99% with modern NGS platforms. Sex is automatically identified as part of PGT-A chromosomal analysis.
Medical Indications: Accepted in All Countries
Sex selection for medical reasons is accepted virtually everywhere and endorsed by ASRM, ESHRE, and ACOG.
X-linked genetic disorders -- conditions carried on the X chromosome that affect males almost exclusively:
| Condition | Who Is Affected |
|---|---|
| Haemophilia A and B | Males predominantly |
| Duchenne muscular dystrophy | Males almost exclusively |
| Hunter syndrome (MPS II) | Males almost exclusively |
| Fragile X syndrome | Both sexes; males more severely |
| Becker muscular dystrophy | Males almost exclusively |
For families carrying these conditions, selecting female (XX) embryos essentially eliminates the risk of an affected child when specific mutation testing is unavailable.
More targeted alternative: PGT-M (testing for the specific causative mutation) is preferred when technically feasible (ASRM 2023, ACOG 2020) -- it allows unaffected embryos of either sex to be transferred.
Social Sex Selection: The Ethical Debate
ASRM Ethics Committee 2023: Permits sex selection for family balancing under specific conditions with appropriate counselling. Considers it ethically permissible in certain contexts.
ACOG 2020: Opposes sex selection for personal preference. Permits it only for serious X-linked disease prevention.
ESHRE Ethics Task Force: More permissive. Acknowledges social sex selection is defensible in some contexts, particularly when a family already has multiple children of one sex.
Legal Status by Country
| Country | Medical Indication | Social / Family Balancing |
|---|---|---|
| India | Illegal | Illegal -- criminal offence |
| United Kingdom | Permitted (HFEA) | Illegal (HFE Act 1990) |
| United States | Permitted | Legal -- no federal prohibition |
| UAE | Limited medical use | Illegal under MOHAP |
| Oman | Serious X-linked only | Illegal |
| Thailand | Medical indication permitted | Legal at some licensed clinics |
| Singapore | Serious X-linked permitted | Illegal |
India: Criminal Offence With Serious Penalties
The PCPNDT Act 1994 (Pre-Conception and Pre-Natal Diagnostic Techniques Act), reinforced by the ART (Regulation) Act 2021, makes sex selection at any stage a criminal offence -- including preimplantation.
Penalties: imprisonment of up to 3-5 years and fines for both the clinic and the couple. No exception exists for family balancing. The law was enacted in response to systematic female foeticide that created severe national sex-ratio imbalance.
Any clinic in India offering sex selection for non-medical reasons is operating illegally. FertilityConnect complies fully with the PCPNDT Act and ART Act 2021.
United States: Legal, With Clinic Discretion
No federal law prohibits preimplantation sex selection. PGT for family balancing is widely offered at US fertility clinics. Additional cost: approximately USD 3,000-6,000 for PGT-A (which includes sex determination). Individual clinics may decline to offer it on ethical grounds.

Frequently Asked Questions
Is sex selection through IVF legal in India?▾
No. Sex selection at any stage, including preimplantation PGT-SD, is a criminal offence under the PCPNDT Act 1994 and the ART (Regulation) Act 2021. Penalties include imprisonment up to 3-5 years and fines for both clinic and couple. No exception exists for family balancing. Any clinic in India offering this service is operating illegally.
Can you find out an embryo's sex during IVF?▾
Technically yes -- PGT identifies sex chromosomes (XX = female, XY = male) with over 99% accuracy. In India this is illegal except for serious X-linked medical conditions. In the USA it is legal for family balancing. In the UK sex determination is permitted only for serious X-linked disease, not for social selection.
What is the difference between PGT-A and PGT-SD?▾
PGT-A screens all 23 chromosome pairs for numerical errors (aneuploidy) to identify chromosomally normal embryos. PGT-SD specifically identifies sex chromosomes (XX or XY). Because PGT-A analyses all chromosomes including sex chromosomes, it automatically reveals embryo sex. PGT-M separately tests for a specific inherited gene mutation and is used for known genetic conditions.
