Can you regain your virginity? Know all about it

There is no denying that there are a shocking number of myths and misconceptions surrounding the female virginity. In fact, it is not only men who are misinformed about the female delicate bits but those with a vagina don’t have a lot of knowledge about it either. Hence, it comes as no surprise that we aren’t exactly enlightened when it comes to the thin, fleshy tissue that stretches across the opening of the vagina. It is known as the hymen and it is a small, circular piece of tissue that partially covers the vaginal opening.

The link between hymen and virginity

The common notion is that hymen breaks during the first vaginal penetration and a lot of people also associate “breaking of hymen” with the “loss of virginity”. However, this is not always the case. This thin tissue can wear down due to a variety of factors besides sexual intercourse including riding a bicycle, doing gymnastics, using a tampon and insertive masturbation. It is also important to understand that some women are even born without a hymen in the first place.

Does hymen determine your virginity?

It is important to understand that there aren’t always obvious physical signs of the loss of virginity when a woman has sex for the very first time. The presence or lack of your hymen has nothing to do with your virginity as it usually thins over time and may not stretch during your first sexual intercourse. Moreover, there is no medical concept of virginity and here are no medical tests available which can confirm your virginity. 

Can you regain your virginity?

Since in some cultures, sexual abstinence before marriage is important, some women place a lot of importance on bleeding during the “first night” after marriage. Hence, they are often on a quest of repairing or regeneration of the hymen. There is a procedure known as hymenoplasty which involves suturing the remains of the original hymen. It is also used to create a new hymen without leaving any visible trace that the person has had the procedure. This surgery is often performed under local anaesthesia. As it grafts together, the stretched hymen will appear intact.

Recovery after hymenoplasty

Since it is not a major surgery, most patients recover within a week. You can resume work after 3 to 4 days but it strongly advised to refrain from physical activities for at least two weeks. You need to refrain from sex until 8 weeks after the surge

Remember:

While there is no dearth of home remedies present on the internet that claim to regrow or regain your virginity, it is important to understand that none of them provide the correct information. There is no way your hymen will grow back on its own if it has been stretched during any physical activity or if you are born without one.

New patches made with human cells help boost recovery from heart attack

A research has been conducted to enhance recovery from heart attack.For the first time, large human cardiac-muscle patches have been tested in the lab on large animals in a heart attack model. It showed that it resulted in improved recovery from heart attack injury.

This is the first large-animal study of muscle patches carried with a goal of treating human heart attacks by suturing cardiac-muscle patches over a specific area of dead heart muscles. It was carried out in order to reduce the pathology that often leads to heart failure.

The research was conducted by a joint department of Medicine and the School of Engineering.Each patch is 1.57 by 0.79 inches in size and nearly as thick as a dime.

The team found that transplanting two of these patches onto the infarct area of a pig heart significantly improved the function of the heart`s left ventricle, the major pumping chamber.

The patches also significantly reduced infarct size, which is the area of dead muscle; heart-muscle wall stress and heart-muscle enlargement; as well as significantly reducing apoptosis, or programmed cell death, in the scar border area around the dead heart muscle.Furthermore, the patches did not induce arrhythmia in the hearts, a serious complication observed in some past biomedical engineering approaches to treat heart attacks.

A mixture of three cells - two million endothelial cells - known to help cardiomyocytes function and survive in a micro-environment, 2 million smooth muscle cells - known to line blood vessels, and 4 million cardiomyocytes - known as heart-muscle cells, each patch is grown in a 3-D fibrin matrix.

Subsequently, it is rocked back and forth for a week and all cells start to beat synchronously after day one.The three cell types are differentiated in the making from cardiac-lineage human-induced stem cells, also known as hiPSCs.

Dynamic rocking and the apt mixture produce more quantity of mature heart-muscles cells, with more contractive force and superior physiological function, as compared to patches made with mono-layered cells which are not dynamically rocked.

In the past, attempts to use hiPSCs to treat large animal models of heart attacks have shown very low rates of engraftment or survival. The current research shows a relatively higher rate of engraftment - 10.9 percent - after four weeks of transplant which resulted in improved heart recovery.

These patches also release tiny blebs called exosomes which carry RNA and proteins from one cell to other. In tissue culture experiments, it is found that such exosomes which are released from large heart-muscle patches help in the survival of heart-muscle cells.

Additionally, these patches are found to reverse or prevent detrimental changes in protein phosphorylation in the sarcomeres of heart-muscle tissues bordering the infarct of the heart. This result suggested that hiPSC-derived heart cells may improve contractile function after heart attacks.
