Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
GM508 Cult-Active- oocytes are placed into the 1.0% calcium ionophore (GM508 Cult-Active) for 15 mins following ICSI. The oocytes are then removed, washed in our normal culture media and returned to the culture drops as per PIVET protocol. Patients may opt to have this treatment as many times as they want
Intervention code [1] 286030 0
Treatment: Other
Comparator / control treatment
The patients previous IVF/ICSI cycle in which the calcium ionophore had not been used. i.e the patient who is been treated with the calcium ionophore's previous cycle where fertilisation was reduced.

This cycle will more than likely be within 6 months of the calcium ionophore treatment cycle
Control group
Uncontrolled

Eligible patients must have had previous complete failed fertilisation, reduced fertilisation (<50%) or have severe male factor infertility (Sperm concentration < 2 x 106 million/ml, Sperm motility < 5%
Strict criteria normal morphology < 4%). Patients with surgically collected sperm (epididymal collected sperm or testicular collected sperm) will also be included
Minimum age
21 Years
Maximum age
45 Years
Sex

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients must have had previous complete failed fertilisation, reduced fertilisation (<50%) or have severe male factor infertility. Patients with surgically collected sperm (epididymal collected sperm or testicular collected sperm) will also be included. Patients will be consulted by their Clinician on the benefits and risks of calcium ionophore usage. They will be given an information sheet and consent. They will need to read this information sheet. Patients will have the opportunity to discuss and ask any questions or raise any concerns about the ionophore for a second time at their routine embryologist consult before the egg collection. When or if they decide to use the ionophore, they can sign the consent. No calcium ionophore treatment will be given without a signed, witnessed consent in the patient file.
