Females inherit one X chromosome from each parent. Males inherit the X chromosome from their mothers and the Y chromosome from their fathers. Males have one X and one Y chromosome (XY) and females have two X chromosomes (XX). These genes are located on the X chromosome. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This condition often resolves with appropriate treatment. The majority of cases involve middle-aged or elderly people, or young women who have recently given birth or are in the later stages of pregnancy. In rare cases, a person can develop hemophilia later in life. The lower the amount of the factor, the more likely it is that bleeding will occur which can lead to serious health problems. The severity of hemophilia that a person has is determined by the amount of factor in the blood. People with hemophilia have low levels of either factor VIII (8) or factor IX (9). This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains many proteins called clotting factors that can help to stop bleeding.

Once an embryo is fertilized using this method, it’s transferred to the uterus. If your fallopian tubes are blocked or missing, it’s still possible to get pregnant via IVF, as fertilization will take place outside your body. In this case, eggs are fertilized in a lab. The uterus lining “feeds” the blastocyst, which eventually grows into a fetus.Īn exception to this rule would happen with in vitro fertilization (IVF). When the zygote implants, it’s called a blastocyst. The zygote then burrows into the uterus lining. From here, the zygote will move down the fallopian tube and into the uterus. Once fertilization takes place, this newly fertilized cell is called a zygote. Fertilization takes place in the fallopian tubes, which connect the ovaries to the uterus.įertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Many people think fertilization occurs in the uterus or ovaries, but this isn’t true. Fertilization occurs in the fallopian tubes
