The sperm preparation method plays an important role in the outcomes of IUI (intrauterine insemination), IVF (in vitro fertilization) and ICSI (intracytoplasmic sperm injection). Studies have shown that a long waiting period in seminal plasma affects the fertilization capacity of spermatozoa. Therefore, preparation techniques need to be fast, efficient and thorough: Microorganisms are discarded by...

TESA is performed under local anesthesia. A needle is inserted in the testes and fluid and tissue are aspirated. This procedure is performed when spermioducts are obstructed or to increase pregnancy chances when ejaculate has been used in unsuccessful previous attempts. As testes are the organ in which the sperm are produced, the chance of...
The best time for semen analysis Semen analysis is performed after a 3-5 day sexual abstinence. This time interval is critical to obtain accurate information on semen. If the abstinence is longer than 5 days, the number of spermatozoa increases, but the motility and vitality decrease and the risk of DNA damage is increased. On...
Preparation of the program Doctor Consultation After you decide to attend the IVF program, your doctor will examine you and will finish all the processes necessary to start the program. During the examination, the ovaries, the uterus, the length of uterus and cervix will be observed. Also, tests such as hormone levels, hysterosalphingogram (HSG), spermiogram...
Blastocyst culture Blastocyst formation occurs at day 5 or day 6 after insemination. One of the greatest advantages of blastocyst culture is to determine slow growing or growth-arrested embryos which ultimately give low chance of pregnancy. In our center, to choose the best embryo having the best survival capacity, we prefer to culture zygotes until...
Blastocyst Transfer What is a blastocyst? About 5 days after the fertilization, blastocysts hatch by coming out from their outer layer (zona pellucida). With the recent advances in the field, embryos can be kept in the laboratory until this developmental stage. Embryo transfer in blastocyst stage is more advantageous because it is quite parallel to...
Assisted Hatching Hatching of the blastocyst, occurring on the 5th or 6th day after insemination, is a prerequisite for the implantation of the embryo to the uterus. Hatching defines the phenomena by which the blastocyst budds from and finally leaves the glycoprotein membrane (zona pellucida) enclosing it. Assisted hatching by either thinning or opening of...
Assessing sperm morphology Spermatozoa morphology is a very good indicator of sperm quality. In our center, spermatozoa morphology assessment is done according to criteria in the “WHO Manual for Examination and Processing of Human Sperm, 5th edition” using “Spermac stain”, which stains the nucleus red and the acrosome, neck and tail green. After staining, spermatozoa...
Evaluating the semen sample Semen analysis is a basic test performed in the evaluation of infertile couples as it gives valuable information on the function of the male reproductive system and the quality of sperm produced. Although semen can be rapidly assessed, the full analysis is complex and is carried out by experienced personnel. Basic...
