It is essential to make an appointment, so that the semen sample can be analysed by the laboratory staff within one hour. A private room is available if you prefer to provide your sample at the clinic. To arrange an appointment simply call the clinic that is most convenient to you.
A wide variety of techniques for the preparation of sperm are currently available, of which the most commonly employed are density—gradient centrifugation DGC and swim-up SUP. To date, these methods appear to be effective in selecting functional sperm for assisted reproduction techniques ARTbut they may have negative effects on sperm DNA. In this study, the ability of these semen processing techniques to eliminate spermatozoa containing single- and double-strand DNA damage was assessed by the two-tailed comet assay and the sperm chromatin dispersion test in semen samples from patients seeking assisted reproduction treatment.
Laws on reproductive rights in Switzerland face a test amid the growing use of online sperm banks and greater acceptance of non-traditional family structures. Sinceonly married couples in Switzerland can use donated sperm cells. But the existing law is being challenged in a world where increasing numbers of gays, singles and reproductively challenged heterosexual couples hope and expect to have children — and can access online sperm banks and reproductive clinics abroad.

Copenhagen is as flat as the proverbial pan-cake. Squeeze past the other tourists in the ascent of the final staircase, and you are treated to a view stretching out in all directions. This is partly because of a change in UK law, which meant that donors were no longer anonymous.
Find out what to do once you've chosen the sperm donor you want for your fertility treatment. The availability of a sperm donor will vary. Straws are sold and replaced on a daily basis.
Men choose to bank their sperm for a variety of reasons, such as having a condition or undergoing a procedure that may affect future sperm production or putting off fatherhood until later in life. Whatever your reason for cryobanking, Maze offers a full line of services to collect, freeze and store sperm. Contact us to learn more or schedule an appointment.
Once thawed, the contents of the vial will be liquid. Warm the vial to body temperature in your hands or under your arm before inseminating. And please do not store the vial in your refrigerator or freezer prior to thawing—a standard freezer is not sufficiently cold to keep sperm frozen.
We tested this prediction in 2 replicated lines of male guppies Poecilia reticulata that were artificially selected for high and low BSP. We investigated whether males with a different BSP differed in their sperm priming response. We found that when the perceived mating opportunities increased, males from low-sperm lines had a stronger sperm priming response than those from high-sperm lines.
