![]() This is called implantation.īefore implantation though, the blastocyte breaks out of its protective covering. Once there, its next job is to attach to the endometrium. Then the fertilized egg (now called a blastocyte) continues to divide as it passes slowly through the fallopian tube to the uterus. It remains in the fallopian tube for about three days after conception. ![]() Within 24 hours after fertilization, the egg begins rapidly dividing into many cells. If the fertilized egg and sperm is a combination of an X and Y, it’s a boy. Generally, women have a genetic combination of XX and men have XY. The sex of your baby depends on what sperm fertilizes the egg at the moment of conception. When the sperm penetrates the egg, changes occur in the protein coating of the egg to prevent other sperm from entering.Īt the moment of fertilization, your baby’s genetic make-up is complete, including its sex. On average, fertilization happens about two weeks after your last menstrual period. If you don’t become pregnant during a cycle, this lining is what is shed during your period. This lining is the place where a fertilized egg settles to develop. Progesterone helps prepare the endometrium (lining of the uterus). This secretes (releases) the hormones progesterone and estrogen. It’s generally in the middle of your cycle.Īfter ovulation, the opened (ruptured) follicle develops into a structure called the corpus luteum. Ovulation generally happens about two weeks before your next menstrual period begins. The mature follicle now opens and releases the egg from the ovary. The other follicles stop growing at this point. This follicle then suppresses all the other follicles in the group. Out of this group of eggs, one will become mature and continue on through the cycle. Think of these follicles as small containers for each immature egg. The eggs develop in small, fluid-filled cysts called follicles. First, a group of eggs (called oocytes) gets ready to leave the ovary for ovulation (release of the egg). In a cycle that ends with pregnancy, there are several steps. This cycle is continuously happening during your reproductive years - from puberty in your teen years to menopause around age 50. You will either have a menstrual period or become pregnant. How does conception work?Įach month, your body goes through a reproductive cycle that can end in one of two ways. ![]() Your healthcare provider will ask you about this date and will use it to figure out how far along you are in your pregnancy. Though it may seem strange, the date of the first day of your last period will be an important date when determining your due date. It’s about two weeks ahead of when conception actually occurs. This is called the gestational age, or menstrual age. ![]() Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.The start of pregnancy is actually the first day of your last menstrual period. With no clouds, the average temperature of the Earth would increase significantly.Īnd so to summarize what I expect would happen. Clouds reflect sunlight and help cool the Earth.And so vast stretches of land would become desert. Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall.Without clouds, I foresee a few things happening: So the first answer is that there would be no clouds. The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So what would happen if there were no condensation stage? The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. ![]()
