A man's fertility is not guaranteed to remain the same over time. Medical conditions, treatments, surgical procedures, and occupational exposures can all affect sperm production in many ways. The effects can be temporary or permanent. Storing a sperm sample beforehand is one of the most impactful steps for men who are about to face any of these situations, that they can take to protect their reproductive future.
At KIMS Cuddles at KIMS Hospitals, Electronic City, semen freezing is available as a standalone fertility preservation service and as part of the broader fertility treatment programme for men across Electronic City, Hosur Road, Neeladri Road, and South Bengaluru.
Why Men Freeze Sperm
The reasons for storing sperm are varied and all clinically legitimate.
Before cancer treatment is the most common and most urgent reason. Chemotherapy and radiation therapy can severely and permanently damage sperm production by killing the rapidly dividing cells of the testicles. There can be temporary or permanent damage depending on the type of treatment, the dose, and the area treated. Because there is no way to predict in advance if these men will recover full fertility or not, semen freezing before treatment begins is strongly recommended for any man of reproductive age who may want children in the future.
Before surgery affecting the reproductive tract, including prostate surgery, vasectomy, testicular surgery, or pelvic procedures that may affect nerve supply to the reproductive system.
Declining sperm quality in men with progressive conditions or who are producing their best quality samples now may benefit from storing samples while quality is at its highest.
Logistical reasons include men who cannot be present for IVF procedures on the day of egg retrieval, those in careers or situations requiring extended absence, or those who need a backup sample in case of difficulty producing a sample on the day of treatment.
Single men who wish to preserve their fertility before undergoing a medical procedure or simply as an elective measure while they are at their most fertile.
The Semen Freezing Process
Semen freezing at KIMS Cuddles at KIMS Hospitals, Electronic City is a straightforward procedure that can typically be completed in a single visit.
A semen sample is produced through masturbation in a private collection room at our clinic. Men who prefer to produce a sample at home can do so provided it is transported to the laboratory within one hour in a sterile container at body temperature. The recommended period of abstinence before the sample is two to five days.
On arrival at the andrology laboratory, the sample is assessed for volume, concentration, motility, and morphology. This baseline assessment provides important clinical information and guides decisions about how many samples to store and what they are most likely to be suitable for in future treatment.
The sample is then mixed with a cryoprotectant solution that protects the sperm cells during the freezing process, divided into multiple straws, and cooled in a controlled-rate freezer before being plunged into liquid nitrogen for long-term storage. Dividing the sample into multiple straws preserves the option to use portions of the stored sample in different future treatment cycles without thawing and refreezing the entire collection.
How Many Samples to Store
The number of samples stored depends on the quality of the semen analysis and the intended future use. A man with excellent sperm parameters may need only one or two samples. They are enough for multiple IUI or IVF cycles. A man with poor sperm parameters may require storing several samples collected over a period of days to build a larger reserve.
Our andrology team advises on the appropriate number of samples to collect based on the initial semen analysis result and anticipated future treatment requirements.
Using Frozen Sperm in Treatment
Frozen sperm can be used in a range of fertility treatments following thawing. For IUI, a washed preparation from the thawed sample is placed into the uterine cavity. For IVF, the thawed sample is either used for conventional insemination or, if sperm parameters after thawing are reduced, for ICSI. For cases where only a small number of sperm survive thawing, ICSI allows a single sperm to be selected and injected directly into a mature egg, maximising the use of a limited sample.
Post-thaw sperm survival rates vary depending on the quality of the original samples and the freezing process. Our laboratory provides information on post-thaw survival estimates where possible, based on the pre-freeze assessment.
Storage Duration and Consent
Stored sperm samples at KIMS Cuddles at KIMS Hospitals, Electronic City, are maintained in liquid nitrogen in our secure storage facility. Storage is governed by a clear consent that mentions the intended use of stored samples and the duration of storage. The framework also clearly states what happens to samples if they are not used within a defined period, and the wishes of individuals regarding the samples in case of death or incapacity.
Consent is reviewed periodically, so it is important that individuals keep their contact details and consent documentation up to date. Samples are never released for use without the explicit consent of the individual at the time of use.
