Infertility
Conditions
Brief summary
The aim of this research is to compare sibling oocytes using two sperm selection methods for choosing the best quality spermatozoa before they are injected into oocytes and the influence of each of these methods on embryo quality and IVF outcome.
Interventions
DEVICEICSI petri dish
Half of the oocytes will be placed into the standard ICSI petri dish and they will be injected with sperm with normal morphology.
DEVICEPICSI petri dish
Half of the oocytes will be placed into a PICSI petri dish (whose bottom is coated with hyaluronic acid) and the mature spermatozoa with CD44 receptors that are attached to the bottom of the dish will be injected into them.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of fertilization rate | Three years | Injected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The fertilization rates of the ICSI and PICSI methods will be compared. |
| Comparison of embryo quality | Three years | Injected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The embryo quality of the ICSI and PICSI methods will be compared. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Implantation rate | Three years | Injected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The implantation rates of the ICSI and PICSI methods will be compared. |
| Pregnancy rate | Three years | Injected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The pregnancy rates of the ICSI and PICSI methods will be compared. |
| Miscarriage rate | Three years | Injected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The miscarriage rates of the ICSI and PICSI methods will be compared. |
| Live birth rate | Three years | Injected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The live birth rates of the ICSI and PICSI methods will be compared. |
