The IUI survey follows from a recent discussion in Embryomail and from a request from a subscriber. IUI often are overshadowed by IVF but many clinics use it as a pre-IVF treatment option. We have asked for a live birth rate knowing than this will depend on the type of stimulation used, age of the clients, multiple pregnancy rate, etc but it is meant to be a guide only. It started as a survey on sperm preparation but has been expanded to provide a broader summary on methodology.
The Question was:Does your clinic offer IUI - Total yes replies= 31
The Option: Our lab staff are multi-skilled so anyone who is rostered on for IUI [Results: Yes= 13 No: 13 Total= 26]ANALYSIS

Minimum criteria for insemation-an assessment is done prior to insemination and a patient needs to have a tmc of >10 million post density gradient and a tmc of > 1 million post swim, if they don't meet these markers, they are not recommended for IUI treatment
Minimum total sperm concentrated inseminated-whatever we end up with after density gradient is inseminated but would like to see greater then 10 million motile sperm

It would have been interesting to know the number of IUIs with husband sperm and IUIs with donor sperm performed annually. We performed 280 last year, 20% donor.
Other questions that would be interesting:
1. Timing of IUI after detecting of LH surge in natural cycles
2. Limit to how many IUIs a couple receives before they must move on to IVF, donor IUI or adoption
The following questions were hard to answer:
What final gradient do you use? We use either a 2-step 45%/90% gradient, or a 45% only gradient depending on the semen quality. Cryopreserved semen always gets the 45% only
What insemination volume do you prepare The insemination volume cannot be greater than 0.5 mL. That answer should be included. The uterus will not accommodate more. Everyone should be doing this.
Ovulation I left this blank because we do all 3 depending on patient characteristics
Minimum total sperm concentration inseminated I left this blank because for low sperm numbers, we let the patient decide after counseling about benefits and risks. The physician is notified if there are less than 5 million motile sperm so he/she knows that this discussion with the patient will be necessary.

#1132 writes: Minimum motile sperm inseminated is 1 million in 0.3 ml of culture media.
#1133 writes: We aim for up to 4 cycles of FSH stimulated IUI with an hCG trigger - over response leads to potential conversion to IVF
Insemination will be carried out irrespective of final number of motile sperm but we aim for >5million.
Typically trial preparations are carried out where samples have borderline parameters before joining the IUI programme. Where an insemination is carried out with significantly <5 million motile sperm, the treatment plan is reviewed before proceeding with any further treatment.

#1135 writes: What insemination volume do you prepare; please disregard this answer. I misread the question. The insemination volume is <0.5ml. Thank you.

We do gradiŽnt and wash only - depending on Q.
