Kegel Exercises: Squeeze and Relax
Kegel exercises help strengthen pelvic muscles, especially those around the urethra, vagina, and rectum. Doing it regularly can help improve sexual function and prevent or reduce the loss of force of urine (urinary incontinence) or stool (fecal incontinence).
To perform this exercise, a woman squeezes the muscles used to stop the flow of urine for about 10 seconds, then relax for 10 seconds. Exercise is repeated 10 to 20 times in a row at least 3 times a day. Muscles usually recover in 2 to 3 months. Kegel exercises can be performed anywhere, whether a woman is sitting, standing, or lying down.

Finding the right muscles to squeeze out can be difficult. The muscles can be identified by inserting a finger into the vagina and squeezing or by trying to stop the flow of urine. If the pressure is felt around the finger or the urine flow stops, the muscles of the right is being blackmailed.

Gestation
A baby goes through several stages of development, beginning as an egg is fertilized. Eggs develop into a blastocyst, embryo, and fetus.

Fertilization
In every normal menstrual cycle, one egg (ovum) usually released from one ovary, about 14 days before the next menstrual period. The release of an egg is called ovulation. Egg is swept into the funnel-shaped end of one fallopian tubes.
At ovulation, the mucus in the cervix becomes thinner and more elastic, which allows the sperm into the uterus quickly. Within 5 minutes, the sperm can move from the vagina, through the cervix into the uterus, and to the ends of the funnel-shaped tube-site regular-fertilization. The cells lining the fallopian tube facilitate fertilization.
female anatomy
If the sperm penetrate the egg, fertilization results. Tiny hairlike cilia that line the fallopian tubes to encourage cell fertilized egg (zygote) through the tube toward the uterus. The cells of the zygote divides repeatedly as the zygote moves down the fallopian tube. zygote enters the uterus in 3 to 5 days. In the uterus, the cells continue to divide, becoming a hollow ball of cells called a blastocyst. If fertilization does not occur, the egg degenerates and passes the uterus with the next menstrual period.
If more than one egg is released and fertilized, pregnancy involves more than one fetus, usually two (twins). these twins are fraternal. Identical twins occur when one fertilized egg separates into two embryos after they had started to divide.

Blastocyst development of
Between 5 and 8 days after fertilization, blastocyst attached to the lining of the uterus, usually near the top. This process, called implantation, equipped with 9 or 10 days.
Blastocyst wall is one cell thick, except in one area, where it is three to four cells thick. The cells in the thickened part in developing into an embryo, and cells outside burrows into the lining of the uterus and develops into the placenta. The placenta produces several hormones that help maintain the pregnancy. For example, the placenta produces human chorionic gonadotropin, which prevents the ovaries from releasing an egg and stimulate the ovaries to produce estrogen and progesterone continuously. The placenta also carries oxygen and nutrients from mother to fetus and waste material from the fetus to the mother.
Blastocyst wall becomes the outer layer of the membrane (chorion) that surrounds the embryo. The inner lining of the membranes (amnion) develops around 10 to 12 days, forming the amniotic sac. The amniotic sac filled with clear liquid (amniotic fluid) and expands envelop the developing embryo, which floats in it.
As the placenta develops, it extends a small hair-like projections (villi) into the uterine wall. Branch projection and rebranch in complex treelike arrangement. This arrangement greatly increases the contact area between the wall of the uterus and placenta, so that more nutrients and waste material can be exchanged. The placenta is fully formed by 18 to 20 weeks, but continued to grow during pregnancy. At delivery, weighing about 1 pound.
Developing Embryos
The next stage in development is the embryo, which develops under the lining of the uterus on one side. This stage is characterized by the formation of most internal organs and external body structure. Organ formation begins about 3 weeks after fertilization, when embryos first recognized as having human form. Shortly thereafter, an area that will become the brain and spinal cord (neural tube) begins to develop. The heart and major blood vessels begin to develop with a 16 on the day or 17. The heart begins to pump fluid through blood vessels by 20 days, and red blood cells which first appeared on the following day. growing blood vessels in the embryo and placenta.
