Other way round.
FPFW discuss the statistics that exist for the UK:
In 2011, GIRES estimated that only 20% of the UK transgender population are likely to seek medical treatment for their condition at some stage...[An estimate is] there are 200,000 male-born transgender people in the UK will no body modifications whatsoever. Of the 50,000 trans-identifying males that do seek medical treatment most of these would be expected to be undergoing hormone treatment and/or breast implants. Only a very small proportion of this 20% will have genital reconstruction surgery.
No one knows for sure how many transwomen keep their penis, but there are fewer than 10 surgeons in the UK who can do the relevant operation. Even if they each performed one operation every single day this would still only represent an absolute max of 3,500 surgeries each year. The actual number performed is likely to be very much smaller than this. An estimate of just a few hundred operation each year would not be unreasonable.
