Artificial Insemination
  • Artificial Insemination with Donor (AID), usually
    intravaginal or intracervical.
  • In the West, sperm banks.
  • Donor is anonymous and tested for STDs
  • Used when the man is irremediably azoospermic
  • At the time of ovulation the whole semen is put
    intravaginally or intracervically
  • Parents and donor do not know each other

4
Artificial Insemination
  • Artificial Insemination with Husband (AIH)
  • Intra-couple procedure
  • Usually when husband is mildly oligospermic (gt5
    million spz/ml) or if woman has cervical problem
    or if couple has unexplained infertility. Rarely
    used with coital or anatomic defects
  • At the time of ovulation (spontaneous or induced)
    intrauterine deposistion of washed spems (IUI)

5
In-Vitro Fertilization
  • First successful case 1978 Louise Brown in Great
    Britain
  • Originally, was devised for tubal infertility
  • Later was expanded to male, unexplained, and
    other forms of infertility.
  • Now also used by a small number of couples to
    avoid transmission of inherited genetic diseases
  • The techniques are standardized and simplified

6
In-Vitro Fertilization
  • Techniques
  • Induction of ovulation to recruit a great number
    of follicles which will yield a great number of
    oocytes
  • Different protocoles of ovulation induction
  • Monitoring cycles with serum estradiol and serial
    ultrasounds
  • When follicles are mature triggering of
    ovulation with HCG

7
In-Vitro Fertilization
  • Techniques
  • 34 hours later oocyte pick-up (OPU) by vaginal
    ultrasound or laparoscopy
  • Aspiration of follicles. Oocytes are put in
    glassware dishes (In-Vitro)
  • Manipulation of oocytes and their in-vitro
    maturation

10
In-Vitro Fertilization
  • Techniques
  • Oocytes are put with sperms either directly
    (50.000 spz/oocyte) or by micro-injection called
    ICSI (1 spz/oocyte)
  • If fertilization occurs an embryo will result
  • 48 to 72 hours later this embryo who would have
    reached the 8-cell stage is replaced in the
    uterus of the woman

Cloning
  • Reproductive
  • Therapeutic
  • Totipotent cells (0-2 days)
  • Pluripotent cells (5-10 days)
  • Multipotent cells (10 days)
  • Unipotent cells
  • Specialized cells

Medical Problems of IVFwith Ethical Implication
  • AID STDs
  • IVF (and to a lesser extent AIH)
  • OHSS
  • Ovarian Cancer (?) due to drugs
  • Multifetal Pregnancies Prematurity, Preeclampsia
  • Abortion preclinical and clinical

16
Ethical Problems
  • AID
  • Possibility of one donor to have several children
    that might marry
  • Problems of child rejection by the mothers
    husband (who in fact is the legal father)
  • Child wanting to retrace his biological father
  • Late appearance of a genetic disease in the donor
  • Sperm manipulation Sex selection

17
Ethical Problems of IVF
  • Embryos
  • Surnumerary freezing (dissociation of
    generations), disposal (posthumous)
  • Manipulation Preimplantation genetic diagnosis
    (PGD)
  • Research on embryo
  • Sex Selection
  • Fetal reduction in multifetal pregnancies

18
Ethical Problems of IVF
  • Parenthood
  • As many as five persons have been parents to one
    child
  • Posthumous (what if one parent dies)
  • Separation of couple
  • Oocyte donation
  • Surrogacy

19
Surrogacy
  • Types
  • Eggs, sperms or both may be donated
  • Sperms from the intended father inseminates the
    surrogate mother who is the gestational and
    genetic one
  • IVF-ET combines various modalities of surrogacy
    as many as 5 persons have been parents to one
    child
  • Major arguments for and against
  • For Reproductive freedom is a cherished right
    and some women may derive satisfaction from being
    surrogates and help others (altruistic)
  • Against Harm to the child, mother, her family
    and the society

20
Surrogacy
  • Financial agreements and altruistic motives
  • Payment
  • For what is payment made?
  • Not contingent on the delivery of an acceptable
    product
  • Rather on time and efforts put on the entire
    process
  • Why is payment offered or requested?
  • Is payment likely to lead to the exploitation of
    surrogate?
  • If too low exploitation by not providing
    adequate compensation
  • If too high exploitation by being irresistible
    and coercive
  • Access barrier where this is available only to
    affluent couples.

21
Ethical Problems of IVF
  • Surrogacy
  • Financial incentives and altruistic motives
  • Psychological aspects
  • Interruption of mother-fetus bonds
  • In non-financial agreements, changing of mind
  • Legal situation
  • Surrogate mother cannot break contract
  • Fetus as a commodity
  • Fetus as an (end)-product
  • Hazards are for the surrogate mother

22
Ethical Problems of IVF
  • Oocyte Donation
  • Sources during intervention (stimulated cycle or
    not), fetuses, cadavers.
  • Types donation, selling, trade
  • Confidentiality problems
  • Psychological and legal problems when the source
    is aborted fetuses or cadavers

23
Ethical Problems of IVF
  • Embryo Freezing
  • Several oocytes are produced that might result in
    several embryos. Three embryos are replaced. The
    rest frozen.
  • Frozen embryos for replacement later on, for
    research or disposal of.
  • Replacement 3 or 4. 1 or 2 for pregnancy. The
    others abortion. What if one or both parents die
    or separate
  • Research on or Disposal of Embryos who has the
    decision.

24
Sex Selection
  • Indications
  • Medical gender-related diseases
  • Non-medical Family balancing
  • Methods
  • Pre-fertilization newest is flow cytometry
  • Post-fertilization and Pre-transfer IVF and PGD
  • Post-implantation Karyotyping by CVS and
    Amniocentesis

25
Sex Selection
  • Medical testing not expressly for the purpose of
    sex selection if sex is known, the information
    belongs legally and ethically to the patient, and
    she should be informed if she requests it.
  • Medical testing expressly for the purpose of sex
    selection
  • Position 1 Never participate in a sex selection
  • Position 2 Participate in a sex selection for
    medical reasons
  • Position 3 Participate in a sex selection
    whenever requested
