Contraception
      
      Contraception is the means to avoid pregnancy either by natural abstinence, 
      or by using artificial means. Natural contraception by means of abstinence 
      is very difficult to achieve and is not the practical method in present 
      times. Therefore, artificial methods have proved to be very advantageous 
      to avoid unwanted pregnancies in normal course, as well as in the cases 
      where the woman suffers from some organic disease, and pregnancy is advised 
      to be avoided. 
      
      
Various methods of contraception 
         Hormonal pills (mostly a combination of estrogen and progesterone) 
        for women is the most effective method of contraception, as it inhibits 
        the formation of the egg (ovum) for as long as the pills are continued. 
        Now days, injections of long acting hormones are also available, which 
        remain in the body for 60-80 days and exert the same effect as that of 
        the pills. The advantage of the injections is that they have to be taken 
        only once in three months. The side effects of hormonal contraceptives 
        are temporary weight gain, sodium (salt) retention, white vaginal discharge, 
        reduced bleeding during the monthly periods, etc.
         Intra uterine contraceptive devices (IUCDs) are used in women who 
        want to practice contraception after having one or more children. It involves 
        the insertion of a metallic loop covered with very the copper wire, into 
        the uterus. The side effects are heavy bleeding during monthly periods, 
        and sometimes, in between two menstrual cycles, secondary vaginal infection 
        marked by leucorrhoea (white discharge per vagina), pain in lower abdomen, 
        etc. It is not a 100% safe method and pregnancy might result even in presence 
        of the IUCD, though the pregnancy in such cases proceeds normally thereafter 
        and normal childbirth is possible.
         Vaginal spermicides, available in the form of tablets to be inserted 
        into the vagina near the mouth of the uterus, are less protective, and 
        chances of conception while using these are very high. 
         Use of condoms for males is another method of contraception, though 
        even this method does not offer 100% protection against pregnancy. A common 
        hindrance to its usage is the belief that condoms hamper sexual pleasure, 
        and a rare side effect is a latex allergy for either partner.
         Operative procedures like tubectomy in females and vasectomy in 
        males serve as permanent contraceptive measures and offer 100% protection. 
      
      
      
Ayurvedic methods 
        Though in ancient times, abstinence was considered to be the only correct 
        and morally accepted method of contraception, some ancient scholars have 
        described the simple prophylactic measures to avoid undesired pregnancy. 
        However, the efficacy of these formulae is a needs much evaluation and 
        research.
         The powder of long pepper, Embelia ribes, and lead oxide (Suhaga) 
        in the dose of 1GM along with milk, should be taken during menstrual periods, 
        to avoid pregnancy.
         The paste of hibiscus flower along with starch taken during the 
        first three days of menstruation acts as a contraceptive.
