What Biological method in family planning?

Answer 1

Natural Methods/Biological method of birth control :- There are many variations of natural Birth Control. The most effective methods teach women to chart the signs of fertility that ebb and flow with the natural hormonal changes of each menstrual cycle. There are two main approaches 1) the sympto-thermal approach where waking temperature and cervical mucus are charted, and 2) the mucus approach where only cervical mucus is charted.

Lactational Amenorrhea Method (LAM)

Lactational Amenorrhea Method (LAM) is used by a woman who has just given birth and is exclusively breastfeeding. This method is highly effective for the first six months after childbirth, provided the woman breastfeeds the baby at least every four hours during the day and every six hours through the night, and that her menstrual period has not yet returned. After six months fertility may return at any time.

Temperature Method

In the Temperature Method a woman takes her waking temperature to identify a rise in temperature indicating ovulation has passed. Elevated waking temperature for three days in a row is considered confirmation of the post-ovulatory less fertile phase.

Rhythm (Calendar) Method

Rhythm (Calendar) Method is a much less effective natural birth control method. It predicts a woman's fertile days using calculations based on the length of past cycles and not daily observations of fertility signs as used by FAM/NFP. The Standard Days Method/Cycle Bead Systemis a variation of the Rhythm Method. These are the least effective natural birth control methods and are not generally recommended.

Withdrawal

In this contraceptive method, the man withdraws his penis from a woman's vagina before ejaculation. Both partners must be in agreement on this method, and must be prepared to deal with an unplanned pregnancy, which can occur in 1 out of 5 users. This method isn't very effective because there may be sperm in the pre-ejaculate, which can lead to pregnancy. It also requires a lot of self-control and practice. Studies show a failure rate of 19% in typical users. Withdrawal also offers no protection from STIs.
