Blanche Dumas: A French Prostitute With 3 Legs, 4 Breasts & 2 Vaginas


The story of Blanche Dumas is incredibly unique. In fact, it is so bizarre, you may think it is pure fiction. Dumas was equipped with four breasts, three legs, and two vaginas that were functional. Talk about a jaw-dropping sexual oddity. Dumas also had an extremely strong libido.

Dumas’ Life

According to various sources on the Web, Dumas was born on the island of Martinique (an insular region of France) in 1860. Her father was French, and her mother was one-quarter black. At the age of 25, Dumas was visited and also documented by Bechlinger of Para, Brazil. She was then added to the pages of Anomalies and Curiosities of Medicine (an encyclopedic collection of very rare and extraordinary cases in medicine).

Dumas’ Medical Condition

The medical encyclopedia Anomalies and Curiosities of Medicine claimed that Dumas had a modified duplication of the lower body. Below is a list of her bizarre anomalies.

1. A pelvis that was wider than normal.

2. Two legs that were underdeveloped.

3. A third leg was attached to her coccygeus (a muscle of the pelvic floor). This leg did not have a mobile joint. However, it still had a bend in it where the knee would have been.

4. Two functional vaginas (including two vulvas that were well-developed). It is believed that both vaginas had equally developed sensitivity.

5. A duplicate bladder and bowel.

Did Dumas Really Have 4 Breasts?

According to some online sources, Dumas not only had a pair of well-developed breasts, but also a pair of rudimentary breasts (which were close together) that were located above her hypogastrium (pubic region). The rudimentary breasts were said to have nipples.

However, other sources say Dumas’ so-called rudimentary breasts were actually just a stump of another leg. In order to make the claim that they were a real pair of additional breasts, promoters would maximize its appeal by embellishing the stump with fake nipples.

The Most Bizarre Sexual Relationship The World Has Ever Seen

Since the beginning of time, man has formed relationships with others. After all, it is only human nature to desire the affections of another. That adage ‘there is someone for everyone’ comes to mind when considering the relationship between Blanche Dumas and Juan Baptista dos Santos. Although these two individuals only met up once, it seems that they were probably made for one another. These two remarkable people lived during the 19th Century.

With four breasts and two vaginas, Dumas chose to move to Paris to become a courtesan. Interestingly, during her lifetime, there was a man named Juan Baptista dos Santos who also had dual genitalia. When she heard he was coming to Paris for a European tour, Dumas was eager to have sex with him.

Dumas was born with two vaginas and four breasts. Baptista dos Santos was born with two penises. Since both of Dumas’ vaginas were functional and Baptista dos Santos’ penises were as well, it seems as if they would be a perfect fit. It has been said that both had a ravenous sexual appetite. As such, there is no doubt that these two would make the perfect couple — in the bedroom at least.

If Dumas and Santos really did have an affair, it would be perhaps one of the most bizarre sexual relationships of all time.

Juan Baptista dos Santos: A Man With Two Penises

Juan Baptista dos Santos

Born in Portugal around 1843, Juan Baptista dos Santos was a horseback rider who was known for having two distinct genitalia, as well an extra fused limbs. Physicians first examined Santos when he was just six months old. When he was a young child, he was considered handsome. Other than his bizarre abnormalities, he was fit and well proportioned.

The clinical term for Baptista dos Santos’ condition is diphallia or penile duplication. This is a rare genetic condition. The first incidence of diphallia was documented by a Swiss doctor in 1609. Dr. Johannes Jacob Wecker encountered a cadaver with diphallia. This genetic condition only affects 1 of every 5 or 6 million boys. Since this condition was discovered in 1609, there have only been 1,000 documented cases of penile duplication.

The Physical Characteristics

In the majority of cases, the penises are the same size and are positioned side by side; however, on occasion, one of the penises is smaller. This smaller penis usually sits atop the larger one. Men with this condition are usually sterile, either due to difficulties having intercourse or because of some other type of defect.

1. Santos had two penises (functional for both sexual activity and urination). He urinated simultaneously from both of his penises.

2. Although Santos appeared to have a third leg, instead, it was two limbs that were fused together as one. Interestingly, the fused limbs had a small anus.

In order to prevent his leg from hanging and swinging all over the place, Santos would often wear a customized swing.

3. The extra fused limb had a patella (kneecap). Santos had a limb joint that was freely movable. However, it did not have motor control nor power of motion. Surgeons had advised Santos that the best solution to the problem would be a surgical procedure.

Santos’ Strong Sexual Appetite

Although Santos declined surgery, he was given a detailed examination at the age of 22. According to the report of his examination, just like Dumas, Santos was also said to have a pronounced libido. What is even more fascinating about his unique case is that he not only possessed two penises, but he also used them both during sexual intercourse. So after finishing with one penis, he would go on and continue having sex using the other.

Perhaps for some women, Santos’ condition wasn’t an issue. Instead, it may have been more like a bonus.

Santos In Sideshows And Circuses

With such an incredibly rare condition, it is no surprise that many were interested in hiring Santos to be a performer in various sideshows and circuses in France. What is surprising is that Santos turned down a contract that would pay him 200,000 Francs (200,621.08 in US dollars) to perform in a French circus. Although he turned down the contract that would pay him excellent money, he did occasionally exhibit himself for rare “special” exhibitions.

Other Congenital Defects Are Linked To Penile Duplication

Having two penises in and of itself is not dangerous; however, there are other conditions associated with diphallia that could lead to medical problems. For example, with penile duplication, other congenital defects may be present.

Many of these defects relate to the urinary tract and the digestive system. In addition, babies with this defect are at an increased risk of having spina bifida.

An individual with penile duplication may urinate from one or both penises. In the case of Baptista dos Santos, it is said that he was able to urinate from both, simultaneously.

Somewhere between 5 and 29 percent of males with penile duplication experience the following medical issues as well:

  • An abnormality of the pubic bone.
  • A double ureter.
  • An abnormality in the location of the penis’ opening (i.e., epispadias).
  • Abnormal sperm production.
  • An abnormal rotation of the kidneys.
  • An extra kidney.
  • A horseshoe kidney.
  • An abnormality in which the baby is born with his kidneys on the outside of the body. A surgical procedure (i.e., bladder exstrophy) is required to correct this problem.
  • An atrial septal defect (i.e., a hole in the heart).
  • An undescended testicle (i.e., cryptorchidism)
  • An inguinal hernia, which is a protrusion of the abdominal cavity through the inguinal canal.

Treating Penile Duplication

The only treatment for this condition is surgical intervention, which usually involves excising the extra penis and urethra. Men who choose to keep their extra appendage are not putting themselves in any danger. They can live a long, healthy life, even if they decide to keep their extra appendage.

Here is a link to a report of a very rare case of complete penile duplication and congenital presence of two anuses. The Egyptian neonate was 21 days old.

Two Bizarre Medical Cases You Won’t Believe Are Real

Though Blanche Dumas and Juan Baptista are long gone, there are people today who live extremely rare medical conditions. The following medical stories may seem unbelievable.

YouTube Star Has Two Vaginas, Two Wombs & Two Cervixes

YouTube star Cassandra Bankson regularly provides beauty tips for her nearly 1 million subscribers. After experiencing ongoing kidney pain, she sought medical attention.

Doctors discovered she had two vaginas, two wombs and two cervixes. Bankson’s condition is known as uterus didelphys.
