Sub fertility Investigations & Referral

Local guidelines are outlined below. 

Sub fertility is increasingly common and NHS referrals can be made, however, we can only do so if you meet certain criteria.

  1. You must be trying to conceive for more than 1 year
  2. Women must be aged under 42 and have a BMI of less than 30
  3. Have no more than 1 child in your existing relationship.

Before a referral can be made, we need to carry out some basic investigations in general practice. They are outlined below. This involves blood tests at different times in the cycle, a urine chlamydia test and a recent cervical smear.

Men need to have a seman analysis, this now needs to be done at Hillingdon Hospital.You will need to collect a sample pot and form from reception and follow the instructions as outlined below.


Once we have the results, we can make a referral. All the investigations need to be done in the 3 months before the referral is made.
