Cloning of Dolly the Sheep01:08

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual,  the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
In Vitro Fertilization01:24

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
Reproductive Cloning01:27

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic cell—any cell that is not a sex...

Summary

Assisted reproductive techniques (ART) help breed horses from mares previously deemed infertile. Understanding the cause of mare subfertility guides selection of the most effective ART, like embryo transfer or intracytoplasmic sperm injection.

Area of Science:

  • Veterinary Science
  • Animal Reproduction

Background:

  • Assisted reproductive techniques (ART) enable breeding from valuable but infertile mares.
  • Identifying the specific cause of mare subfertility is crucial before ART referral.

Purpose of the Study:

  • To review common ART in equine practice: embryo transfer, oocyte transfer, and intracytoplasmic sperm injection.
  • To inform practitioners on selecting the most appropriate ART for subfertile mares.

Main Methods:

  • Review of current literature on equine ART.
  • Analysis of the complexity and risks associated with each technique.

Main Results:

  • Embryo transfer, oocyte transfer, and intracytoplasmic sperm injection are key ART in equine reproduction.

  • Successful application depends on matching the ART to the mare's specific infertility factors.

    • Conclusions:

    • Practitioners must accurately diagnose mare subfertility to choose the optimal ART.
    • Knowledge of ART complexity and risks facilitates successful outcomes for infertile mares.
