The egg retrieval procedure takes place in an examination room with intravenous short-duration analgesia (10 to 15 minutes), without loss of consciousness and painlessly. Within 30 to 60 minutes after the completion of the procedure, the patient may leave the Unit's premises.
Sperm is produced and prepared the same day as the oocyte retrieval. During sperm preparation, an adequate number of spermatozoa with good morphology and motility are selected for insemination or sperm injection. Normally, fertilization rate is about 60%.
Before a couple starts an IVF program, the man is subjected to a very specialized test, called "semen analysis". This is, perhaps, the most important test in terms of male fertility assessment. This test enables the experts to check the quality (mobility and morphology of spermatozoa) the quantity (volume, number of spermatozoa) and other characteristics of the semen. This way, experts can identify and then address possible problems.
