Ask a Question

Last reviewed 2026-10-27

Tell us where you are and what you are weighing up. You will get back a written reply: the probability arithmetic applied to your own numbers, the specific questions to put to any clinic, and an honest view of whether this treatment is likely to do what you want.

Used only to answer you. We do not publish your details and we do not pass them to a clinic without telling you which clinic and asking first.

What you get back

  • Your probability of an embryo of the sex you want, for your age band
  • The four outcome figures to demand from any clinic, by name
  • What a complete attempt costs once medication and the frozen transfer are included
  • Whether sex selection is lawful where the clinic you are considering operates
  • A straight answer if the honest advice is not to do this

How we are paid

This site is free to read and carries no advertising. If we introduce you to a clinic and you go ahead with treatment, we may be paid a referral fee by that clinic. We tell you that before any introduction, not after. It is also why every page here tells you to compare what we say against a second opinion.

We will not

  • Call you unless you ask us to
  • Promise an outcome, or quote a success rate we cannot source
  • Offer anything to anyone in a country where this is a criminal offence
