Why Adopt a Sperm?

Every day, all throughout the animal world, millions of sperm are going to waste, swimming their way to fruitless oblivion.

These sperm, if properly collected and stored, could be used to help save the planet’s endangered species from extinction. Once they are in a frozen sperm bank, important genes are stored for the future.

We are on a mission to do just that — and we’re hoping you’ll be able to help our sperm-collecting efforts.

Certificate of Adoption

By adopting a sperm you’re not actually going to receive a frozen animal sperm in the mail. Instead, all adopters will be parent in name and spirit only. Your donation will help support our efforts to properly store and maintain sperm of endangered species in scientifically appropriate facilities until a prime candidate for impregnation is found.

All donors will receive a link to a Certificate of Adoption that they can print, frame and proudly display.

The life cycle of the banteng proceeds at a leisurely pace befitting such a docile creature. The gestation period is 265 days. Calves are weaned at about six to nine months, and sexual maturity occurs at two to three years of age with domestic animals maturing faster than wild ones

Bongo

The Bongo is a large species of antelope that is found inhabiting the jungles and forests of Eastern, Western and Central Africa
They are the largest forest-dwelling antelope species
The Bongo is a shy and elusive creature that is seldom seen by people due to its highly nocturnal lifestyle
Most mating tends to occur between October and January, after which the female Bongo will give birth to a single calf following a gestation period that lasts for around 9 months
Bongo calves grow relatively fast and their horns begin to show by the time they are three or four months old. Weaning occurs at six months but calves tend to remain with the nursery group for longer

Florida Panther

Florida panthers primarily eat white-tailed deer. They are also known to eat feral hog, rabbit, raccoon, armadillo and birds
Estimated at 100-160 adults in the only known breeding population (South Florida)
Males average 130 lbs; females 70-75 lbs
Lifespan 10-15 years
Panthers are habitat generalists, meaning that they use a variety of habitat types, including forests, prairies and swamps
They are solitary and territorial animals that travel hundreds of miles within their home range. Panthers are mostly active between dusk and dawn, and rest during the heat of the day. Males have a home range of 200 square miles and females about 75 square miles
Mating Season: Throughout the year with a peak in winter/spring
Gestation: About 90 days
Litter size: 1-4 kittens
Rarely do all kittens survive. Kittens are born with dark spots that soon fade away as they become adults. They stay with their mother for up to two years

Gerenuk

The gerenuk inhabits semi-arid bush land below 1,200 meters. It avoids grassy areas, preferring instead woody cover, particularly shrubs
In the long-term, survival of the gerenuk is likely to be increasingly dependent on the presence of viable populations in national parks and reserves which are effectively protected. Such areas currently comprise only a small part of the range
Young gerenuks can be born at any time of the year, after a gestation period of 6.5 to 7 months
Mothers do not need long before they can fall pregnant again, and are capable of producing at least four young within three years

Giant Eland

The Giant Eland is the largest species of antelope in the world
The Giant Eland can move quickly, running at over 43 mph (70 km/h), and despite their size are exceptional jumpers, easily clearing heights of 1.5 m (4.9 ft)
They live in the broad-leafed savanna, woodlands and glades of central and western Africa, as well as forests and on the fringes of deserts
They inhabit places near hilly or rocky landscapes and those with water sources nearby
They are not territorial and have large home ranges
The Giant Eland is a herbivore
After a gestation period of nine months one calf is usually born at night
The calf will remain with its mother for around four to six months, after which the young eland might join a group of other juveniles
Female Giant Eland reach sexual maturity at about two years, and males at four to five years of age

World’s tallest mammal
Roam the open grasslands in small groups of about half a dozen
Herbivores
25 year lifespan

The infants can run with their mothers 10 hours after birth

Gorilla

Closely linked by DNA, gorillas are one of the four species of great apes that are the closest living relatives of humans
Gorillas are herbivores and eat leaves, shoots, roots, vines and fruits
Gorillas are ground-dwelling and live in groups of 6-12 with the oldest and largest silverback leading a family of females, their young and younger males called blackbacks
Reproduce throughout the year
Gestation period of 8.5 months
Threatened by habitat loss due to increasing human populations, poaching for the bushmeat trade and diseases like ebola

Litter size: 1 foal
The zebra’s biggest threats are habitat loss due to ranching and farming and competition for water with livestock. They are also hunted for their skins

Impala

Impalas are found at grassland and woodland edges, usually very close by water
Impalas eat tender young grass shoots in the wet season and herbs and shrubs at other times. During the dry season they must drink daily
In East Africa young are born year round, but birth peaks usually coincide with the rains
The female leaves the herd and seeks a secluded spot to bear her fawn
If the calf is born at a time when there are few other young around, the mother will stay with it in seclusion spot for a few days or even leave it lying out for a week or more before returning to the herd
The young are killed by jackals and the smaller cats, baboons, eagles and pythons.
The female is similar to the male but does not have horns
The male’s graceful lyre-shaped horns are 18 to 37 inches long

Jackson's Hartebeest

Found in medium and tall grasslands, including savannas, they are more tolerant of high grass and woods than other alcelaphines (archetypical plains antelopes)
One of the most sedentary antelopes (making it easy to hunt), but it does move around more when larger groupings form during the dry seasons or in periods of drought, to seek water and better grazing
Females are free to seek the best grazing in their home range, but males cannot leave their territories for long if they intend to keep them.
The hartebeest feeds almost entirely on grass, but is not very selective and quite tolerant of poor-quality food
The hartebeest has suffered from the expansion of cattle raising, as hartebeests and cattle compete for the same food
