The placenta attaches to the uterus 4-5 days after conception (the sperm and egg meeting). It is fully functional by 12 weeks.

Where does sperm travel to attach to the wall of the placenta?

Sperm does not travel to the placenta; rather, it fertilizes an egg in the fallopian tube. Once fertilization occurs, the resulting zygote travels to the uterus, where it implants itself into the uterine lining, not the placenta. The placenta develops later as the embryo grows, facilitating nutrient and waste exchange between the mother and the developing fetus.


What is ovine placenta?

Ovine placenta refers to the placenta of sheep (Ovis aries), which plays a crucial role in supporting the developing fetus during gestation. It facilitates the exchange of nutrients, gases, and waste products between the mother and the fetus. The ovine placenta is classified as a cotyledonary placenta, characterized by distinct structures called cotyledons that attach to the uterine tissue. This type of placenta helps ensure efficient maternal-fetal interaction, which is vital for the health and growth of the lamb.

How can a placenta drop if only 12 weeks in the pregnancy?

At 12 weeks of pregnancy, the term "placenta drop" may refer to the placenta shifting position within the uterus as it grows and develops. While the placenta typically continues to develop and attach higher in the uterus, some women may experience changes in its position. However, significant concerns about a "low-lying" placenta usually arise later in pregnancy. If there are concerns about placental position, it's important to consult a healthcare provider for further evaluation and guidance.


What is a circumvallate placenta and could it cause any problems?

In circumvallate placenta, the placenta presents with elevated margins because the location as to where the placenta attaches at implantation is too small for the entire placenta to attach causing the placental edges to be loose. The could possibly cause the placenta to function poorly and not supply the baby with adequate o2. The placenta ends curve and curl inwards. The problem is if the placenta continues to develop in more and more curve and then separates from the uterus. That would mean the need for an emergency delivery of the baby so it becomes very critical the earlier this happens. I don't know the odds of the placenta separating, and nothing may happen at all, it's just important to make sure the baby is getting the nourishment it needs via the placenta and act immediately should any bleeding occur. The doctor said it's not common to see this and there is nothing I have done in the past or anything I can do to avoid problems with separation.

Can a human fetus really be brought to full term in a cow's uterus?

No. The human embryo would die because it cannot attach itself to the uterine wall of the cow due to the fact that the placenta of a human is much different from the placenta of a cow, and that a human and a cow are genetically very different from each other.

Can the placenta move during pregnancy?

Yes. But the movement is relative. Placenta does not change the position. But lower placenta may move up. So that placenta previa may become normal placenta.
