Mitochondria are the part of the cell that produces ATP which the cell can then use as energy to do work. Muscle cells require a lot of ATP to carry out contraction and therefore a large number of mitochondria are required to produce this ATP.

In keeping with our theme of form following function, it is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving. When your cells don’t get enough oxygen, they do not make a lot of ATP.

You inherited your mitochondrial DNA from your mother, who inherited hers from her mother and so forth. Maternal inheritance also gave rise to the idea that there exists a “Mitochondrial Eve,” a woman from whom all living humans inherited their mitochondrial DNA.

Sperm and vaginal sex can help induce labor when the time comes. Oxytocin, one of the key hormones involved in progressing labor, is released during sex, and orgasms mimic contractions. Also, the prostaglandins in sperm can help ripen the cervix.

There’s nothing unhealthy, wrong, or dirty about swallowing semen, as long as you’re comfortable with it. It’s not possible to get pregnant from oral sex, whether or not you swallow. (That’s because your mouth isn’t connected to your reproductive organs.)

Once you’re 20 weeks along, avoid positions that have you lying flat on your back, such as the missionary position. When you lie on your back, the enlarged uterus puts pressure on your aorta, which compromises blood flow to the placenta.

In the first trimester when your belly is still small, any sex position will do. After about 16 weeks as your uterus gets bigger, however, missionary position or any position where you’re lying flat on your back isn’t a good idea.

What Is the Best Position for Sleeping and Lying Down During Pregnancy? In general, pregnant women should try not to lie flat on their back or directly on their stomach.

A long pillow placed lengthways down the middle of the bed may help you both get comfortable on either side. Another tip is to buy an extra duvet, so there’s no tug-of-war for the covers in the night! If either of you snores, the other partner could try blocking out the sound with pillows or some good earplugs.

Shaving: This is the most preferred method adopted by doctors and midwives before preparing a woman for delivery. If you still have full hair growth over your privates before delivery, your doctor is likely to recommend it. If you plan to shave at home, do it 48 hours prior to going to the hospital.

When pregnancy symptoms such as nausea, weight gain, mood swings and bloating occur in men, the condition is called couvade, or sympathetic pregnancy. Depending on the human culture, couvade can also encompass ritualized behavior by the father during the labor and delivery of his child.
