Freezing and cryopreservation of sperm at minus 196 degrees Celsius is called sperm freezing.
It is possible to cryopreserve sperm semi-permanently. The safety of sperm freezing has been medically proven.
Who should do sperm freezing and when?
(1) If male partner is unable to collect sperm on the day you need it due to various circumstances
If male partner is unable to prepare sperm on the day of artificial insemination or IVF due to business trips, overseas assignments, night shifts, etc., we can freeze and preserve sperm in advance and use it.
(2) If you have a low motile sperm count and want to improve your pregnancy rate
The motile sperm count is calculated by multiplying the sperm concentration by the motility rate. If this number is less than 15 million/1cc, which is the effective rate for artificial insemination, there is a way to increase the probability by using multiple sperm strands together. In addition to using multiple frozen sperm specimens, you may also bring the sperm on the day of the insemination and use frozen sperm if necessary based on the findings.
(3) If you want to save a single dose as "insurance" for fertility treatment
For men, being asked to "prepare sperm on this day" is a huge stress and it is natural for them to feel pressured by it. On the day of artificial insemination or in vitro fertilization, the thought of "what if I can't ejaculate?" can add extra pressure. For those who have such a strong sense of responsibility, we recommend that you freeze and store a single dose as insurance in advance. With sperm freezing, artificial insemination and in vitro fertilization can be performed as scheduled even if sperm cannot be retrieved on the same day or if sperm are not available due to sudden work commitments.
How to freeze sperm.
STEP1
Make an appointment to have your sperm cryopreserved.
Collected at home and brought to our clinic.
Collected in the clinic.
Please make a reservation for your desired date via the web or by phone.
Sperm can be collected at home and brought to the clinic, or it can be collected in the clinic.
STEP2
Payment of freezing fee and submission of consent form on the day.
The cost of freezing is ¥11,880 (tax included) per ampule per year.
You will be asked to fill out a consent form for sperm freezing upon payment.
STEP3
Freezing completed.
The semen that we receive is always checked by a team of two people to ensure that there are no mistakes. The sperm are then counted under a microscope and washed and concentrated in a centrifuge for preparation. Finally, it can be cryopreserved semi-permanently in liquid nitrogen at minus 196 degrees Celsius. The safety of frozen sperm has been medically proven.
*If the sperm is in poor condition and cannot be cryopreserved, we will contact you by phone.
Frozen sperm can be transferred to other facilities.
Since we consider frozen sperm to be the property of the patient, we can transfer them to another facility if the patient wishes. Please contact the facility of your choice to obtain permission in advance. The patient is responsible for transferring the frozen sperm.
Borrow a special container (such as a thermos) from the facility where you want to move it and have them fill it with enough liquid nitrogen. Typically, there is no damage to frozen sperm when moving between facilities.
Deadline for sperm freezing.
Sperm freezing can be done semi-permanently, but the guidelines of the Japanese Society of Obstetrics and Gynecology stipulate that it should be done "until the end of the patient's lifetime.”
In other words, if the male partner (owner of the sperm) passes away for any reason, the frozen sperm will be disposed. The freezing process cannot be continued after the male partner’s death, even if the female partner or family members wish to do so.
Procedures for continuation of sperm freezing.
Sperm freezing is ¥11,880 per ampule for one year (tax included). Before the freezing period expires, we will send you a "Notice of Confirmation of Intention to Continue Freezing and Preserving Frozen Embryos, Eggs, and Sperm" by registered mail. At that time, please decide whether you wish to continue or dispose of it. If you wish to continue, the cost is ¥11,880 per ampule for one year (tax included).
