One of the reasons why a couple cannot conceive a child is the factor of male infertility. If the spermogram shows that the number of spermatozoa is very low for fertilization or they are of poor quality, this is not a reason to be upset. It is possible to conceive a healthy child thanks to modern reproductive technologies, for example, ICSI with the participation of frozen single spermatozoa.
The method is as follows:
- A man donates sperm. If this is not possible, the biomaterial is surgically removed.
- The ejaculate is frozen. In cryptozoospermia, severe male infertility, embryologists process the biomaterial by centrifuging it and searching for spermatozoa in the sediment. If it is possible to find spermatozoa of good quality, they are frozen using a special technology for cryopreservation of single spermatozoa.
- The partner is prescribed hormonal stimulation. On the day determined by the doctor, an ovarian puncture is performed (extraction of follicular fluid with eggs). In the laboratory, the resulting eggs are fertilized with thawed spermatozoa and placed in a special environment for development.
- Fertilization is also possible with fresh sperm, however, in the case of cryptozoospermia, it is advisable to stock up on frozen sperm so that there are exactly enough spermatozoa for all the eggs obtained.
- High-quality embryos are transferred to the uterine cavity for further implantation. At the couple's request, some of the embryos can also be frozen.
Many patients fear that after cryopreservation, the material loses its properties. If the conditions of freezing and storage are met, then there is nothing to worry about. In the EMC cryobank, germ cells are frozen using modern proven technologies and stored in stable optimal conditions at a temperature of -196 C.

Questions and answers
Tumor in the breast
I’ve had a tumor in the lower part of my right breast and a metastasis in the left lymph node removed in 2011. I then had a recurrence in the upper quadrant of the right breast. But the doctors didn’t immediately react to this, even though I told them that I was experiencing some discomfort. After this I had biopsies
under ultrasound guidance at several medical centers, but I keep getting a completely different diagnosis everywhere I go. I still haven’t received any treatment. Test results are good. The metastasis is not growing but just sitting there. They’ve suggested a mastectomy. What’s the point? I don’t want to undergo chemotherapy. I’m on a raw food diet. I don't know what to do. I wish at least one of the diagnoses was confirmed. I want to be sure that I’m getting the right treatment. Because it’s the doctors that have brought me to this situation, even though I’ve had regular screenings for the past 25 years.
...more Before answering any questions regarding treatment, it is necessary to carry out a successful biopsy under ultrasound or X-ray guidance, to obtain multiple tissue samples (not cells) with subsequent histological and immunohistochemical analysis. Only then can we discuss a specific treatment plan! In any case, EMC
staff are always ready to provide advice and carry out the necessary diagnostic tests.
