Fresh vs. frozen sperm
Sperm samples are an essential part of the IVF process. For men with male-factor infertility, the suitable sperm sample can increase the chances of pregnancy. A frozen sperm sample is extracted and cryogenically frozen for future use. Frozen sperm can last for several years without losing viability. The frozen sperm is thawed before the fertilization process. A fresh sperm sample is taken from the man and used immediately. Fresh samples often coincide with the egg extraction process.
What are the benefits?
Using fresh sperm samples during the IVF process brings peace of mind to couples. The clinic and patient will know the quality of the sperm. Some studies also reveal that embryos made with fresh sperm may last longer than frozen sperm. On the other hand, frozen sperm brings convenience. The IVF process becomes more accessible as men can preserve fertility for issues like cancer. Frozen sperm is also great for techniques like intracytoplasmic sperm injection (ICSI). The clinic can find the best sperm to inject into the egg.
Does it make a difference?
Frozen sperm is as effective as fresh sperm for IVF and ICSI. Studies show there is no difference in implantation rates and pregnancy rates. Both samples can help with pregnancy, and more importantly, frozen sperm would not interfere with pregnancy rates. That means IVF patients will have more control over IVF cycles. Thanks to frozen samples, single women and same-sex couples can start families at a more convenient time.
Successful with any sample
In vitro fertilization is an excellent way for infertile couples to start a family finally. There is an ongoing concern with the sperm sample, but both are effective. The success rate comes down to other factors like the patient’s health and the expertise of the fertility clinic. Frozen or fresh sperm samples are just a matter of convenience.
