i have a male that just turned a year old this week. well about six months ago i had him to the vet and she noticed he only had one ball she said that the other one should drop before he is a year old and if it doesnt drop by the time he is a year and a half he would need surgery. i checked yesterday still only one. anybody else ever have this happen? is it possible he was only born with one and wont need surgery? i am just thinking that if it something that is going to have to be done i would rather do it now than in six months in the middle of rabbit it season, i would rather him be layed up now not when there is snow on the ground.

found this info for ya outta the merch vet manual
Cryptorchidism is a failure of one or both testicles to descend into the scrotum and is seen in all domestic animals. It is common in stallions and boars and is the most common disorder of sexual development in dogs (13%). Predisposing factors include testicular hypoplasia, estrogen exposure in pregnancy, breech labor compromising blood supply to the testes, and delayed closure of the umbilicus resulting in an inability to increase abdominal pressure. Bilateral cryptorchidism results in sterility. Unilateral cryptorchidism is more common, and the male is usually fertile due to sperm production from the normally descended testicle.

Cryptorchidism
The undescended testicle may be located anywhere from just caudal of the kidney to within the inguinal canal. Abdominal testicles produce male hormones, and cryptorchid animals have normal secondary sex characteristics and mating behavior. Because of the inherited nature of the condition, unilateral cryptorchids should not be used for breeding. After puberty the retained testis becomes hypoplastic, degenerate, and fibrotic. Affected animals should be castrated as sertoliomas, seminomas, and interstitial cell tumors tend to develop within cryptorchid testicles and because of the heritability of the condition.
Some cases of hereditary hypoplasia of the ovaries and testes are associated with a single recessive gene with incomplete penetrance. It has been described in Swedish Highland cattle and has marked association with white coat color; the incidence has been much reduced by a controlled breeding program. Bilateral, unilateral, partial, or total hypoplasia may be seen. A condition similar to the human Turner’s syndrome, with severe bilateral ovarian hypoplasia associated with chromosomal abnormalities, absence of follicles, and fibrosis with consequent infertility has been described in grade mares and in Thoroughbreds, Arabians, Welsh Ponies, Tennessee Walking Horses, Standardbreds, American Saddlebreds, Paso Finos, Belgians, Quarter Horses, and Appaloosas. Affected mares may be smaller than average and show either an absence of estrous cycles or only occasional estrus. They have a small flaccid uterus, a flaccid cervix with an open os, and small to very small ovaries. The ovaries are smooth and firm and have no follicles or corpora lutea. Cytogenetic studies may be indicated in infertile mares that show some or all of the above signs. The most common chromosomal abnormality in these mares is an absence of one of the sex chromosomes, and these animals are designated XO. There is no treatment.
Prolapse of the prepuce is a common defect in bulls, particularly in Bos indicus cattle. In B taurus cattle, it is common in polled beef breeds. A long, pendulous sheath, a large preputial orifice, and absence or poor development of the retractor prepuce muscles are predisposing inherited anatomic abnormalities. Prolapse of the prepuce predisposes the animal to injury, which can lead to abscess formation, scarring, adhesions, or phimosis. Surgical correction of the prolapse is possible, but as genetic predisposition may play a role, castration should be carefully considered.
Penile deviation is a common cause of copulatory failure in bulls. Two types of penile deviation are described— premature spiral deviation of the penis (corkscrew penis) and ventral deviation of the penis. Both conditions are caused by insufficiency of the dorsal apical ligament of the penis. Trauma is rarely involved. Premature spiral deviation of the penis is the most common penile defect in polled beef bulls and has been reported in most beef and dairy breeds. Spiral deviation is abnormal when it occurs prematurely and prevents intromission on more than one occasion. In affected bulls, the condition can be mild to severe, and premature spiral deviations of the penis may range from <25% to >75% of all services attempted. This may occur within one mating season or over several seasons. Most affected bulls develop the defect between 3 and 6 yr of age. In ventral deviation of the penis, the free part of the penis curves downward and prevents intromission. Deviations of the penis are diagnosed by careful observation of bulls at the time of service or during test mating. Surgical correction can be done, but should not be performed if inheritance is possible.
The opening of the penile urethra may be dislocated on the ventral surface of the penis (hypospadias) or on the dorsal surface (epispadias).
Persistent penile frenulum is not uncommon and is regarded as an inherited defect. Affected bulls are unable to protrude the penis from the sheath and, in most cases, cannot achieve intromission. Attachment can be minimal (eg, 0.5 cm), or the preputial mucosa can be attached the full length of the ventral raphe of the free part of the penis. Surgical correction should not be performed in bulls intended for seedstock breeding. Many male foals may appear to have a persistent frenulum at birth, but the condition resolves within a few days. If the condition persists, correction should not be attempted until the foal is at least 1 mo old.
Short retractor penis muscle may occur congenitally or after injury to the penis or prepuce. Affected bulls have normal libido, but during attempted service the penis is only partially protruded from the sheath and the ejaculatory thrust does not occur. Failure of erection in bulls may be a congenital condition but is generally a sequela of trauma and/or hematoma of the penis.

thanks madcatter i think i am going to make an appointment with the vet and see what she thinks she told me that it could cause problems down the road if not taken care of, i might as well get it taken care of now instead of waiting.

I had one hound that never droped any I had them remove. One was there but woundn't drop the vet tryed pulling them down didn't work the other one was next to his kiddey he said the dog would get cacner down the line so I waited till he was little over a year and had it done he is a hunting fool sh-t happens some said breed him but I didn't want to happen too other one. The people I bought him from said it never happen before 1300 mile round trip they didn't know like I said sh-t happen
