A freemartin is not considered a true hermaphrodite but is rather a female that shows male characteristics due to sexual development differences in twin pregnancies. These heifers usually possess underdeveloped reproductive organs and may also display other male-like traits. Understanding this distinction is crucial for effective breeding management. The Freemartin Test Form from the UC Davis Veterinary Genetics Laboratory can help clarify the heifer's condition.

To check for a freemartin heifer, start by having a caliper examination conducted, which assesses anatomical features. You can also use the Freemartin Test Form from the UC Davis Veterinary Genetics Laboratory to confirm the results of your physical examination. Observing behavior and reproductive characteristics can offer additional clues but using a genetic test provides definitive answers. Ensuring accuracy in identifying freemartins will support better herd management and reproduction strategies.

Producers can identify freemartins by examining the external genitalia. A prominent clitoris and loosely attached or feathery vulval lips are a dead give away. The genital opening may be located down between the back legs toward where the prepuce would be on a bull.

Measuring the length of the vagina in the young calf is one way to get an idea if a heifer born twin to a bull is a freemartin. In normal Holstein calves less than one month of age, the vagina is about 5 inches (13 cm) long, but in freemartin Holstein calves it is 2 to 3.25 inches (5 to 8 cm) long.

The clinical signs of the freemartin at age three to six weeks are the absence of the external os, and a vagina length of 5 inches (12 cm) or less. The veterinary surgeon is encouraged to make the diagnosis on these clinical signs alone.

A freemartin or free-martin (sometimes martin heifer) is an infertile female cattle with masculinized behavior and non-functioning ovaries. Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin.

One of those "right places", although small, is to identify as early as possible which heifers born twin to a bull are sterile and not spend money raising these freemartin heifers. About 90 to 95 percent of heifers born twin to a bull are sterile.
