Does Fertility Increase After Childbirth?

Author: Gabrielle Marks


For breastfeeding mothers fertility decreases after childbirth.

More Info: Mothers who choose to breastfeed exclusively generally do not ovulate or have menstrual cycles during this time, many of whom use this knowledge in place of birth control.  Researchers and family planners call this method of natural child spacing the lactational amenorrhea method (LAM).

Research indicates that a new mother's chances of becoming pregnant with the LAM birth control method are less than two percent if she is exclusively breastfeeding without supplementation, her infant is under six months old, and has not had a menstrual cycle.

Non-Breastfeeding Women

There are no hard-fast timeframes that a woman who is not breastfeeding may become pregnant after childbirth.  A woman's fertility is based upon her menstrual cycle, which can be erratic after giving birth.  Many women who opt not to use birth control become pregnant within the first ninety days.  Some doctors suggest waiting at least six to twelve weeks to give your body time to heal.

The lactational amenorrhea method

Expert Opinion 

“In contrast, we always have a few mothers conceive within 90 days of birth (usually inadvertently) and they do just fine. It makes a certain amount of sense to wait at least six to 12 weeks after the birth before attempting to conceive again, but this is not a hard and fast rule."

The lactational amenorrhoea method provided as much protection from pregnancy as non-breast feeding women experience with non-medicated intrauterine devices and barrier methods. The contraceptive effect of lactation cannot be attributed to lactational or postpartum abstinence.

During the first year post partum, the rate of pregnancy before the return of menses in lactating women was less than 3%

There is no strong scientific evidence to support the claim that oregano oil works for warts. 

Oregano Oil

Oregano oil has received attention as possessing a variety of healing benefits including its use as a treatment for common ailments such as sinusitis, rosacea, and warts.  Unfortunately, there is currently no strong supporting evidence from the medical research community to support these claims.

According to James T. Li, Mayo Clinic's asthma and allergy specialist, oregano, like other herbs, does have antifungal and antibacterial properties making it at least plausible that it can help to fight symptoms caused by bacteria and fungi.

Oregano Oil Warts Research

Recent research has indicated that an active constituent of oil of oregano called carvacrol may support the immune system. 

A handful of studies have set out to explore the general antifungal, antibacterial properties of oil of oregano and have proven promising. A study in the journal Phytotherapy Research demonstrated the oils effectiveness against inhibiting parasites of the intestines, while a similar study published in the Pakistan Journal of Pharmaceutical Sciences demonstrated the oil's effectiveness against bacteria.

There are currently no research studies published in peer accepted medical journals that have studied the effectiveness of oregano oil on warts.

Using Oil of Oregano on Warts

The book "Common Sense Pediatrics: Combining Alternative and Traditional Medicine in Everyday Practice" by S. Cornelia Franz MD, touts oil of oregano as an effective wart treatment and suggests rubbing a drop of oregano oil on a wart twice daily and it should disappear within a few weeks.  Before experimenting with any alternative treatment, it's always best to consult your personal physician.
