assisted reproductive technology

Examples of assisted reproductive technology in the following topics:

• Infertility

  • Infertility, or the ability to conceive, can be treated by assisted reproductive technologies which can aid conception.
  • These include diseases (such as sexually-transmitted diseases that can cause scarring of the reproductive tubes in either men or women) or developmental problems frequently related to abnormal hormone levels in one of the individuals.
  • If the cause of infertility is identified, several assisted reproductive technologies (ART) are available to aid conception.
  • A common type of assisted reproductive technology is in vitro fertilization (IVF) where an egg and sperm are combined outside the body and then placed in the uterus.

• Infertility

  • Definitions of infertility differ, with demographers tending to define infertility as childlessness in a population of women of reproductive age, while the epidemiological definition is based on "trying for" or "time to" a pregnancy, generally in a population of women exposed to a probability of conception.
  • In other cases, the cause is suspected to be immunological or genetic; it may be that each partner is independently fertile but the couple cannot conceive together without assistance.
  • If the sperm are of good quality and the mechanics of the woman's reproductive structures are good (patent fallopian tubes, no adhesions or scarring), physicians may start by prescribing a course of ovarian stimulating medication.
  • IVF and related techniques are called assisted reproductive technology (ART) techniques.
  • Fertilization takes place outside the body, and the fertilized egg is reinserted into the woman's reproductive tract, in a procedure called embryo transfer.

• Small sample hypothesis testing for a proportion exercises

  • Assisted Reproductive Technology (ART) is a collection of techniques that help facilitate pregnancy (e.g. in vitro fertilization).

• Asexual Reproduction in Plants

  • Plants have two main types of asexual reproduction: vegetative reproduction and apomixis.
  • Many different types of roots exhibit vegetative reproduction .
  • This method of reproduction is known as apomixis.
  • Asexual reproduction can take place by natural or artificial (assisted by humans) means.
  • Different types of stems allow for asexual reproduction.

• Coaching and Scaffolding

  • Seeing that he is successful, she moves on to assist another student.
  • This assistance is a temporary framework provided by the teacher or a more knowledgeable person to assist students in performing a task they otherwise cannot accomplish without assistance.
  • His responsibilities include training new cashiers as well as updating all employees on technology upgrades and new programs.

• Technology

  • Technology can assist the audience with listening, but can also be a distraction at the same time.
  • Beyond technology being utilized by the presented, technology used by the listener can also hinder effective listening.
  • Technology should simplify communication, not make it more complicated.
  • Speakers can avoid distractions caused by technology by doing the following:
  • Technology can be a hindrance and help to effective communication.

• Lenski's Sociological Evolution Approach

  • Lenski's sociological evolution approach views technological progress as the most basic factor in the evolution of societies and cultures.
  • He views technological progress as the most basic factor in the evolution of societies and cultures.
  • Unlike White, who defined technology as the ability to create and utilize energy, Lenski focuses on information, its amount and its uses.
  • Lenski claims that members of a society are united by a shared culture, although cultural patterns become more diverse as a society gains more complex technology and information.
  • Human reproductive capacity exceeds the available resources in the environment.

• Female Hormones

  • The control of reproduction in females is more complex than that of the male.
  • Estradiol is the reproductive hormone in females that assists in endometrial regrowth, ovulation, and calcium absorption; it is also responsible for the secondary sexual characteristics of females.
  • Progesterone assists in endometrial re-growth and inhibition of FSH and LH release .
  • The ovarian and menstrual cycles of female reproduction are regulated by hormones produced by the hypothalamus, pituitary, and ovaries.
  • The pattern of activation and inhibition of these hormones varies between phases of the reproductive cycle.
