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

Eligibility
Key inclusion criteria
All participants will be patients of PIVET Medical Centre and under the clinical management of one or more of the Fertility Specialists who work at PIVET. No outside patients will be involved in this study. 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
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Any patients that has had fertilisation rate of greater than 50% in a previous cycle will be excluded

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.

Summary
Brief summary
Oocyte activation is characterised by a dramatic increase in intracellular calcium concentration followed by short high frequency calcium oscillations. This is triggered when the spermatozoa penetrates the egg. Without this calcium influx the oocyte will fail to fertilise.

Many studies have shown that the fertilsation rate can be improved as well as embryo development and consequent implantation rates, by mimicking the physiological cell-signalling mechanism using an activation agent such as a calcium ionophore.

We wish to use a commercially avaliable calcium ionophore, GM508 Cult-Active, supplied by Gynemed Germany to study this effect on our patients who have undergone a complete failed fertilization cycle or a reduced fertilzation cycle (< 50% of oocytes injected) or where severe male factor infertility is evident.
