Apart from the emergency pills such as positron 2, pregnancy can be prevented naturally by other means. This might sound unbelievable but believe it or not, pawpaw, also known as papaya can prevent pregnancy.
Pawpaw fruits have a juicy taste rich in antioxidant nutrients like carotene, vitamin C, vitamin B, flavonoids, folate, pantothenic acids, potassium, magnesium, riboflavin, vitamin D and such.
The fruit is also a good source of fibre. All the aforementioned antioxidants have numerous health benefits in the body. They boost the immune system hence barring entry of pathogens into the body and masking the cardiovascular system as well.
Pawpaw also contains papain, a compound that inhibits the release of the hormone progesterone.
From a biological point of view, progesterone produced by the ovary usually prepares the uterine lining (endometrium) to receive the fertilized egg (embryo).
Thus, due to papain found in pawpaw, they usually stop the ovary from producing the aforementioned hormone and thus prevents fertilization of an egg.
If you consume unripe papaya twice a day for three to four days after unprotected sex as reported by elitedaily, you will not become pregnant.
This is usually preferred if you want to bar unwanted pregnancy and also if you can not afford to buy emergency pills.
Disclaimer: The best way to prevent an unplanned pregnancy is through regular birth control use and condom use.
