Refigerating sperm

I have recently found a suitable male donor with whom I am to have a child through self-insemination. Please can you tell me if freezing sperm at home is an option, how it is best stored, and for how long and at what temperatures sperm is active? Sorry, but I feel it would be crazy to attempt any kind of 'home freezing' of seminal fluid.

Question: I am an educator for a human sexuality class. A student asked me an interesting question that I was unsure how to answer. Given that we know sperm can survive about 72 hours in a woman's body, how is it possible to keep sperm viable by freezing them?

The recovery and cryopreservation of epididymal sperm are essential tools to preserve genetic stocks of valuable domestic or wild animals under adverse conditions and also as an alternative source of gametes in cases of human infertility. This technique is recommended after death or when it is not possible to recover semen by usual methods. Sperm from the epididymis has been studied by many authors in different species. Cryopreservation is the most effective method for long-term preservation of genetic material from valuable breeding individuals.

How temperature affects equine semen: refrigeration versus cryopreservation. A simple method to select high quality spermatozoa. Cooled and frozen equine semen shows a reduction in fertility, compared to fresh one.

A Japanese research team from Kumamoto University has succeeded in developing a refrigeration preservation technology that maintains the fertilization functionality of mouse sperm for 10 days. Previously, the maximum freezing period was limited to three days, but by extending the preservation period by over three times that amount, it is now possible to send sperm of genetically modified mice to research organizations around the world. Many universities and pharmaceutical companies are engaged in research and development using genetically modified mice that have certain genes manipulated to reproduce human diseases.

Short term storage of human sperm using an easy single step refrigeration process that preserves semen for up to 4 days without freezing or glycerol. Refrigeration Medium TYB with Gentamicin is ideal for short term sperm storage to preserve sperm for up to 4 days. With an easy one-step process of simply thawing the media and adding media at a ratio with the sperm sample, it is quicker and easier than sperm cryopreservation.

This is an advertorial sponsored by Zoetis. Artificial insemination has been done for many years, but the ability to freeze semen and chill and ship semen has dramatically changed the ability to do planned breedings with incredible success. Vaginal, transcervical, and surgical inseminations are now the norm for many kennels, and it is now possible to successfully breed with semen from almost anywhere in the world reducing stress for the bitch and travel costs for the breeder.

Fertility is fleeting, and not just for women. Turns out that men have biological clocks too, and, therefore, also experience an age-related decline in fertility. Specifically, as men age, sperm count and motility decline, making it more difficult for fertilization to occur. And, unfortunately, the DNA integrity of sperm also decreases with age, which can increase the chance that you will pass on genetic mutations to your offspring, leading to developmental problems like autism and schizophrenia.
