Sperm donation involves donating genetic material to another person or couple via artificial insemination. Sperm banks impose limits on the number of children produced by a donor. However, private donations are less regulated. One study found that sperm donors often cite altruism as a motive but also report reasons related to financial gain, selfishness, and […]
Preimplantation Genetic Testing (PGT) involves studying the DNA of embryos created in a laboratory through in vitro fertilization (IVF) before they are implanted into the uterus. It can detect hundreds of different genetic disorders, such as chromosome abnormalities and single-gene diseases. Couples who wish to avoid passing on a hereditary disease to their children can […]
IVF and Insemination are both fertility treatments that help couples have a baby. However, there are some differences between the two that patients should know about before they undergo either treatment. The main difference is that IVF involves removing eggs from the body and fertilizing them in a lab while IUI involves injecting sperm into […]
Frozen embryos are often transported between medical laboratories and fertility clinics for various reasons. These include regulatory arbitrage, access to a specific selection of donor gametes or just life changes such as moving cross-country or overseas. Embryo transportation has been proven safe and effective, as pregnancy rates with shipped embryos are comparable to those achieved […]
Men have two testicles (testes) that produce male sex cells called sperm. They are held in a bag called the scrotum. During puberty, germ cells line the seminiferous tubules and start to change into sperm cells. Seminiferous Tubules The testis is lined by coiled tubules, known as seminiferous tubules. The tubules are the specific site […]
What is an Egg Donor? Egg donation, also known as oocyte donation, makes pregnancy possible for women who cannot achieve conception using their eggs. It can also help same-sex couples and men who want to become parents. Reputable fertility clinics conduct extensive medical screening before accepting an applicant for the egg donor program. This includes […]
A woman who chooses to freeze her eggs faces a similar choice to women who delay childbearing for other reasons. Both have the potential to reduce future suffering, but they also create new harms. Egg freezing can be a complex decision, especially for older women. Ultimately, the decision to freeze one’s eggs should be medically […]
Although more eggs retrieved can help increase the chances of one or two normal embryos implanting and leading to pregnancy, implantation rates have more to do with egg quality than quantity. The fresh, day five (blastocyst) stage of an embryo has a better chance of being genetically normal and resulting in a pregnancy than the […]
