Reproductive Cloning01:27

Reproductive Cloning

32.7K
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...

What is Natural Selection?01:32

What is Natural Selection?

126.5K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Sperm Transport01:15

Sperm Transport

3.3K
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

Overview of the Reproductive System01:31

Overview of the Reproductive System

5.2K
The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

Asexual Reproduction02:38

Asexual Reproduction

37.2K
Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Disorders of the Female Reproductive System01:24

Disorders of the Female Reproductive System

3.9K
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Area of Science:

  • Reproductive Biology
  • Andrology
  • Assisted Reproductive Technologies

Background:

  • Male factor infertility affects a significant number of couples seeking fertility treatment.
  • Effective sperm selection is crucial for the success of assisted reproductive technologies (ART).
  • Various techniques exist to isolate and select viable sperm from an ejaculate.

Purpose of the Study:

  • To provide a comprehensive overview of current sperm selection techniques in ART.
  • To guide embryologists in selecting the most competent sperm based on specific male infertility factors.
  • To discuss methods for isolating competent sperm and selecting single sperm for intracytoplascial sperm injection (ICSI).

Main Methods:

  • Review of established and emerging sperm selection techniques.
  • Analysis of methods for isolating motile and morphologically normal sperm.
  • Discussion of single sperm selection protocols for ICSI.

Main Results:

  • Effective sperm selection methods enhance ART success rates.
  • Techniques vary in their ability to isolate sperm with optimal fertilizing potential.
  • Case-specific selection strategies can address diverse causes of male infertility.

Conclusions:

  • Sperm selection is a critical component of successful ART.
  • Embryologists require tailored guidance for optimal sperm selection in male infertility.
  • Advancements in sperm selection techniques offer improved solutions for couples undergoing fertility treatment.
