The uterus plays a crucial role in reproduction. After fertilization, the zygote travels from the fallopian tubes into the uterus, where it implants into the uterine wall and begins to develop into a fetus. The uterus is composed of several layers, including the endometrium, myometrium, and perimetrium.
The endometrium is the innermost layer of the uterus, which thickens in preparation for pregnancy and sheds during menstruation if pregnancy does not occur. The myometrium is the muscular middle layer of the uterus, which contracts during labor to expel the fetus. The perimetrium is the outermost layer, which covers the uterus and helps to anchor it in place within the pelvis.
In some cases, fertility treatments such as in vitro fertilization (IVF) may involve the transfer of embryos directly into the uterus. This can be especially helpful for couples struggling with infertility due to issues such as blocked fallopian tubes or low sperm count. However, certain conditions such as uterine fibroids or structural abnormalities of the uterus may also impact fertility and may require treatment before attempting IVF or other fertility treatments
