Determining the sex of a ball python?

Question

Diablo is about 4 years old, but I've never had him(?) sexed. He's too old to be "probed", but is there any way to look at the slit near the anal spurs to determine whether he's a male or female? Thanks.

Answer 1

Your snake is not to old to be probed. They can be probed at any age. However, he is to big to be popped.
You cannot accurately determine the snakes sex just by looking. There is always a female with a shorter or longer tail than normal and spur size isn't always a giveaway either. We have a female with huge spurs that we were told was a male. We probed and it is definitely a female.

Your best bet is to find someone in the area that knows what they are doing to probe your snake so you will know for sure.
Good Luck!

Answer 2

One of the matters commonly misunderstood by novice snake enthusiasts is that most snakes can be sexed accurately and with minimal trauma to the animal. This paper will discuss two methods of sexing adult and juvenile snakes - probing and "popping" of the hemipenis.

SNAKE ANATOMY

Posterior to the cloaca, a pair of hemipenes are present in male snakes.



These are paired structures, and lie inverted on either side of the midline. In both male and female snakes, musk glands are also typically present.

SEX DETERMINATION BY PROBING

Sex can be determined in snakes by probing posterior to the cloaca, to determine the presence of hemipenes. Typical sexing probes are stainless steel and either ball-tipped or tapered on the end.



These are available as sets of different diameters and lengths from various suppliers.

The sexing process begins by selecting the probe of proper diameter. As mentioned above, the hemipenes are paired structures located on either side of the midline. By turning the snake over and visualizing their location and size, a proper probe diameter can be selected. Generally, a probe diameter equal to approximately one quarter of the anal plate is appropriate. Choice of too large a probe will prevent free movement of the probe within the hemipenis, while a probe too small will risk puncturing the posterior end of the hemipenis when probing.

After a probe is selected, it should be lightly lubricated with K-Y jelly, vaseline, mineral oil, or water. If the animal is to be probed just prior to breeding, care should be taken not to use a lubricant that contains a spermicide.

The tip of the lubricated probe should then be placed in the cloaca, on either side of the midline.

The probe is then rotated anteriorly, with gentle downward pressure.

If properly positioned, the probe will move posteriorly into the tail in both males and females.

Posterior pressure should be maintained until posterior travel stops.
The probe is marked at the spot where it enters the cloaca,
and the probe is slowly withdrawn.

The probe is then placed on top of the tail in the same position and depth it was inside the pocket,
and the depth of penetration assessed in terms of subcaudal scales.

Females of most species probe to a depth of approximately three subcaudal scales, and almost always less than eight,
while males probe nine or more subcaudals.

There are exceptions, and lists of typical probe depths for various species are given in other publications.

A safer method of sexing juvenile snakes is the "popping" of the male hemipenes. The animal is held inverted in the left hand, with gentle finger pressure just forward of the cloaca. The ball of the right thumb is placed on the tail, about twenty scales behind the cloaca. The right thumb is then rolled forward toward the cloaca. This pressure on the tail will cause the hemipenes of the male snake to be everted.

ME C is awesome.I'm not sure if it was said.Only pop hatchlings to very young snakes as too much pressure to bring out the hemipenis will break the vertibrae.Injuring it and giving it the old kinky tail.If you see one at the reptile show with a kink tail , someone didn't do it correctly and injured it.You may also probe them.Be very gentle.Have a pro show you how first.As for sexing adults, only probe them.As far as boas and python go, Males have the larger spurs for stimulation and females have very small ones that they don't use.

Answer 5

Take your snake to a vet. They can check for you and it should only take a couple of minutes.

Answer 6

yes there is.
where the tail begins to tapper at the end.
males is longer than females.
This is what my vet told our son.

Answer 7

your snake is not to old to be probed but he is to old to be poped..

you can probe a snake of any age.
