Seahorses and their close relatives,
Very few males animals give birth to their young. The main exception in the term dubbed 'male pregnancy' occurs in Syngnathidae fish, such as seahorses. Females carry their young in a brood pouch until they are delivered.
In the entire animal kingdom, male seahorses (and their close relatives) are the only male animals that undergo pregnancy and give birth to offspring.
The uterus would either have to be donated by a willing donor or be tissue-engineered using the male's stem cells and then implanted into the pelvic region. Afterward, an in vitro fertilisation (IVF) procedure would be followed to insert the embryo into the male's transplanted womb.
Both biological and “trans” men are capable of becoming pregnant, according to Planned Parenthood's Director for Primary and Trans Care Dr.
Guinness World Records named Beatie the "World's First Married Man to Give Birth" in 2010. In a TV broadcast from Rome, Italy, Guinness World Records presented him with the title of "Unico Uomo Incinto al Mondo", translated as "World's First Pregnant Man".
Ectopic pregnancies are most commonly found in the fallopian tubes or on peritoneal surfaces in the pelvis, including on the ovaries and omentum [1]. Pregnancy after hysterectomy is extremely rare, with the first case of ectopic pregnancy after hysterectomy reported by Wendler in 1895 [2,3,4].
On this day: A pregnant man gives birth for the first time in history. Most men would be relieved their anatomy means they can avoid the excruciating pain of childbirth. But not Thomas Beatie.
For some, of course, it's normal to only have one or a couple offspring in a lifetime. But swamp wallabies, small hopping marsupials found throughout eastern Australia, are far outside the norm: New research suggests that most adult females are always pregnant.
Seahorses are not one of those animals who change their sex. The female lays the eggs and the male carries the fertilized eggs on his back. They remain male and female.
Slugs, starfish, and other creatures also switch gender when it works to their advantage. However, the cues that trigger the change vary from species to species.
The platypus (Ornithorhynchus anatinus) has a puzzling array of features. Not only does it have that iconic duck bill, it lays eggs like a bird or reptile but feeds milk to its young like a mammal.
The vast majority of animals need to breed to reproduce. But a small subset of animals can have offspring without mating. The process, called parthenogenesis, allows creatures from honey bees to rattlesnakes to have so-called “virgin births.”
Cichlids hold fertilized eggs in their mouth.
Cichlids are from the large fish family called Cichlidae, which includes tilapia and angelfish. When they reproduce, the male puts the fertilized eggs in his mouth, which is where they stay until hatching. This process is called mouthbrooding.
Many species of fish, like the kobudai, are known as “sequential hermaphrodites”: they can switch sex permanently at a specific point in their lives. The majority of “sequential hermaphrodites” are known as “protogynous” (Greek for “female first”): they switch from female to male.
Clownfish are known as sequential hermaphrodites and are born with both male and female reproductive organs. The change is driven by hormones and the change happens in their brain first before it affects their actual reproductive organs. All clownfish are born male, but they can change into a female if necessary.
Seahorses and their close relatives, sea dragons, are the only species in which the male gets pregnant and gives birth. Male seahorses and sea dragons get pregnant and bear young—a unique adaptation in the animal kingdom. Seahorses are members of the pipefish family.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
Did anyone know that some animals have blue blood, especially when it is exposed to oxygen? Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders.
A firstborn (also known as an eldest child or sometimes firstling) is the first child born to in the birth order of a couple through childbirth. Historically, the role of the firstborn child has been socially significant, particularly for a firstborn son in patriarchal societies.
The oldest recorded mother to date to conceive was 73 years, while the youngest mother was 5 years old. According to statistics from the Human Fertilisation and Embryology Authority, in the UK more than 20 babies are born to women over age 50 per year through in-vitro fertilization with the use of donor oocytes (eggs).
It is claimed that Barbara Stratzmann (c. 1448 – 1503) of Bönnigheim, Germany, gave birth to 53 children (38 sons and 15 daughters) in a total of 29 births by 1498. She had one set of septuplets, one set of sextuplets, four sets of triplets and five sets of twins.
Women without children have also been found to have an increased risk of breast cancer, and increased mortality from uterine, ovarian and cervical cancer when compared to women with children. Moreover, the fertility declines with the advanced age at first childbearing.
Summary. Pregnancy after a hysterectomy is extremely rare but can occur, leading to a potentially life-threatening medical condition called an ectopic pregnancy. This occurs when a fertilized egg implants outside of the uterus. Once you undergo a hysterectomy, you cannot get pregnant.
