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.

How soon another attempt is possible?
Twin pregnancy resulted from IVF, but cervical dilatation occurred and water broke at 20 weeks, so the pregnancy was not maintained. How soon another attempt is possible?
At least a year interval between childbirth and repeated IVF program is required. It is advisable to be prepared and to make every effort to get a singleton pregnancy.
Рolyp of the cervical canal
Hysteroscopy revealed a polyp of the cervical canal, it was removed, but there are plenty of micropolips. May I do IVF or they should be treated?
Usually, all polyps are removed at therapeutic and diagnostic hysteroscopy. It makes no sense to leave them in the uterus cavity. I think that if manipulation such as "Hysteroscopy with separate diagnostic curettage" was done, you have no polyps now and may safely prepare for IVF.
