In Inser we have the service of Sperm Bank, which facilitates the freezing of the spermatozoa in medium and long term to facilitate the future paternity in patients with diverse illnesses or difficulties in their fertility.
It is the procedure by which the sample of seminal fluid is processed by exposing the spermatozoa (gametes) at very low temperatures in order to slow down the cellular biological processes.
These samples can be stored for long periods of time to be used for reproductive purposes, with the purpose of having semen available for use when the procedure requires it.
Patients decide to freeze their semen when they have already initiated or completed a treatment that may interfere with sperm production (such as chemotherapy or radiotherapy), when they may have problems with the quality of semen at the time of cryopreservation, such as:
- Absence of sperm in the ejaculate when analysing the sample. In that case it would be unnecessary to freeze.
- Presence of spermatozoa that may or might not have been adversely affected by the treatment received.
- If the sample is affected, and given the possible restoration of the sperm production over time, it may be advisable to perform subsequent seminal analyses.
It is suggested to consult with the treating physician about which is the opportune time to start the sample storage process, according to the treatment received in order to avoid negative effects on offspring.
To improve the possibility that spermatozoa survive the freezing process, semen is mixed with cryoprotector substances and stored in liquid nitrogen at – 196 º C. However, not all sperm survive this process, and it can happen that very few or none of them survived to be used later.
The time that the sperm remain cryopreserved does not seem to affect its viability and does not increase the risk of fetal abnormalities with respect to a natural conception with fresh sperm. The storage time is extendable according to the needs of each individual or couple.
The semen bank allows to freeze sperm for long periods of time. This is done for the purpose of having spermatozoa available to be used later in an assisted reproduction insemination cycle, or for men who want to preserve their future fertility before undergoing procedures that affect their potential reproductive, such as pelvic or genitourinary system surgeries (vasectomy, prostatectomy, among others).
In addition, a person may use the sperm bank when:
- You should undergo treatments that can reduce or void your reproductive capacity (surgery, chemotherapy, radiation therapy).
- Have difficulty in obtaining seminal sample for assisted reproduction treatments.
- Present a progressive deterioration due to known or unknown cause of the characteristics of the spermatozoa.
- Have extremely low spermatic counts that make it advisable to accumulate sperm from various ejaculates.
- Test antibodies to HIV (AIDS), surface antigen for hepatitis B, antibodies to hepatitis C, serology and IgG/IgM for cytomegalovirus and Chlamydia Trachomatis.
- Fill in the consent and contract format for cryopreservation, storage and custody of spermatozoa with our center.
