The short answer
Fertility assessment can involve both partners. If you are having difficulty conceiving, a GP can discuss your history and arrange appropriate investigations. A home sperm-concentration result is one piece of information, rather than a replacement for that assessment.
When to start the conversation
NHS advice is to seek help after a year of regular sex without contraception without conceiving. Ask sooner if the partner trying to become pregnant is 36 or over, or there is another concern, such as previous cancer treatment or a possible STI. You can ask for an initial conversation without deciding which test to buy.
What the GP may ask
Expect questions about how long you have been trying, medical history, medicines, previous contraception and any difficulty with sex. Both partners matter in the assessment. Bring a list of prescribed medicines, supplements and past hormone or anabolic steroid use. An awkward conversation can still be a useful one; you do not need perfect medical words.
What a semen analysis can add
The NHS describes semen analysis as the main test for investigating low sperm count. It looks at sperm amount, movement and shape. A testosterone blood test answers a different question. A finding that needs confirmation may lead to a repeat or specialist assessment; your clinical team explains the plan.
A home check has a narrower job
The concentration-only kit described on SHIFT’s product page does not assess all the features of semen analysis. It cannot tell you whether a pregnancy will happen or assess a partner’s fertility. If you are already concerned about conceiving, the useful next step may be assessment rather than a purchase.
Take a short set of notes
Write down when you started trying, any earlier pregnancies or fertility assessments you want to mention, relevant treatment and the questions you want answered. Ask who will arrange the next investigation, how the result will reach you and what happens if you need another appointment. Keep the plan simple enough that both of you know the next step.
Keep the wider support around you
Trying for a baby can take up a lot of headspace. You can ask for support with the emotional or relationship side as well as the investigations. Free My Timber information and Good to Talk do not depend on buying a test. Neither replaces a fertility service.
