SPERM BANKING
BY
DR FAIZ AHMAD
History: 1776 - First observations on the effects of freezing temperatures on human
sperm .
1866 - First banks for frozen human semen suggested.
1949 - Glycerol first used as protective agent for bovine spermatozoa.
1953 - "Dry Ice" preservation method developed by Bunge and Sherman -
First successful human pregnancy using frozen sperm.
1953 Bunge and Sherman, using dry ice for freezing and storing semen,
reported the first successful human pregnancy resulting from insemination
with frozen human semen..
Since that time, new and improved methods of freezing and storing semen by
immersion in liquid nitrogen at –I96.5°C (Behrman and Ackerman, I969) have
improved the fertilizing capacity of frozen semen and led to the emergence of a
number of commercial human sperm banks in the United States.
1960 - Sperm frozen and stored using liquid nitrogen .
1972 - First commercial cryobanks founded .
1973 - Normal child born from semen stored for over one year
SPERM BANK
Sperm bank, semen bank or cryobank
a. is a facility or enterprise that collects and stores
human sperm from sperm donors for use by women who need
donor-provided sperm to achieve pregnancy.
b. Sperm donated by the sperm donor is known as donor sperm, and
the process for introducing the sperm into the woman is
called artificial insemination, or third party reproduction.
c. From a medical perspective, a pregnancy achieved using donor sperm
is no different from a pregnancy achieved using partner sperm, and it
is also no different from a pregnancy achieved by sexual intercourse.
d. The primary recipients of donor sperm are heterosexual couples
suffering from male infertility, lesbian couples and single women.
SELECTION CRITERIA FOR SPERM
DONORS• Men of all ethnicities and backgrounds are accepted as donors.
• The donors are healthy men between 18 to 45, from a sound
background, and usually graduates.
• A non smoker, non alcoholic who maintains a healthy life style.
• who is willing to undergo frequent and rigorous testing and who is
willing to donate his sperm so that it can be used to impregnate women
who are unrelated to, and unknown by, him
• They should be able to provide their family's medical history (usually
back to two to three generations
• Blood test for blood grouping, Rh status, HIV, diabetes, hepatitis B &
C & other sexually transmitted diseases
• Screening for genetic abnormalities
• They must be able to make a commitment to the program (usually 6
months to 24 month. )
• This semen is analyzed, and accepted only if it has superior qualities: a
count over 100 million per millimetre; and motility of 70% to 80
• donor must agree to relinquish all legal rights to all children which
result from his donations
Screening of donors
Donors are subject to tests for infectious diseases such as :
HIV (HIV-1 and HIV-2),
Human T-cell lymphotropic viruses (HTLV-1 and HTLV-2),
Syphilis,
Chlamydia,
Gonorrhoea,
Hepatitis B virus, Hepatitis C virus
Cytomegalovirus , Trypanosoma cruzi and Malaria.
Hereditary diseases such as:
cystic fibrosis, Sickle cell anaemia, Familial Mediterranean
fever, Gaucher's disease, Thalassaemia, Tay-Sachs disease, Caravan's disease, Familial dysautonomia, Congenital adrenal hyperplasia ,Carnitine transporter deficiency and Karyotyping .
• The donor will undergo a semen analysis and the sample will be thawed to
evaluate post-freezing/thawing semen parameters.
• Sperm susceptibility to damage with freezing varies between individuals, as
well as between samples of a given donor.
• Donors are selected if the post-thaw semen parameters meet a minimum
standard.
• In general, specimens should contain a minimum from 20 to 30 million motile
sperm per milliliter after thawing.
• Post-thaw motility is generally in the range of 25% to 40%.
Indications for Sperm Donation
1.Therapeutic donor insemination (DI or TDI) is used for.
a)Male infertility ;
Azospermia / Blocked of ejaculatory duct/ testicular failure
Oligospermia/sperm or seminal fluid abnormality
Erectile dysfunction/Undecided testes
b)Genetic/Familial disorders ;
c)Female is Rh-sensitized and male partner is Rh-positive ;
d)Single woman who desires a pregnancy but who lacks a male
partner ;
2.Medical Reasons: which will cause permanent sterilisation
or genetic deffect:
a)Infections,
b) STDs (Sexually transmitted diseases),
c)Testicular or pelvic trauma ,heat, irradiation,
d)Radiotherapy, chemotherapy, drugs, tobacco, alcohol etc,
e) Pre-Vasectomy Sperm Banking,
3.Military & Hazardous Occupation Fertility Preservation:
TYPE OF DONOR
Anonymous donor : where the child / receiving couple will never get to
know the identity of the donor.
Non-anonymous donor: termed as known donor, open identity or identity
release donor,.
Private or "directed" donations : privately and directly from a friend,
family member, by advertising , or through a broker.
Place and method of collection
The contract may also specify the place and hours for donation.
Not to have intercourse or to masturbate for a period of usually 2–3
days before making a donation.
A sperm donor generally produces and collects sperm at a sperm bank
or clinic by masturbation in a private room or cabin, known as 'men's
production room' (UK), 'donor cabin' (DK) or a masturbatorium
(USA).
The donor masturbate or use an electrical stimulator, to produce
ejaculate in a special condom , known as collection condom, also use
to collect semen during sexual intercourse.
Processing and Storage
Sperm banks usually 'wash' the sperm sample to extract sperm from
the rest of the material in the semen.
A cryoprotectant semen extender is added before frozen storage.
One sample can produce 1-20 vials or straws, depending on the
quantity of the ejaculate and whether the sample is 'washed' or
'unwashed'
A semen analysis is performed on each ejaculate.
This includes a complete seminal fluid analysis, quantitating sperm
motility, forward progression, sperm density, and morphology.
All specimens are stored in liquid nitrogen storage tanks (-196 ° C).
Once frozen, the vials are immersed in liquid nitrogen in secure tanks
at a temperature of -196° C (-371° F).
The screening procedure also includes a quarantine period, in which
the samples are frozen and stored for at least 6 months.
After which the donor will be re-tested for the STIs.
This is to ensure no new infections have been acquired or have
developed during the period of donation.
Providing the result is negative, the sperm samples can be released
from quarantine and used in treatments
PRINCIPLE OF CRYOFREEZING
During freezing “ Transition of intra and extra cellular liquid to
solid state occurs spontaneously.
Spontaneous change of the physical state of the entire extra and intra
cellular water is prevented by creating ice crystallization.
Cryoprotectants are used for lowering freezing point so that
intracellular freezing occurs at lower temperature, gives cells more
time to dehydrate.
Two categories of cryoprotectants used, depending on their molecular
size and permeability.
1) Permeating (Small molecules)- Glycerol,DMSO,Ethylenglycerol.
2) Non-permeating (Large molecule) - sugars like Sucrose and
Raffnose, Protein and Lipoproteins.
DMSO appears to be more effective, because it penetrates the cell
better than Glycerol.
Concentration of between 5% to 15% have been used, But 7.5% to
10% is more usual.
• Short-term Semen Cryobanking: freezing and storage of sperm
at a sperm bank for less than one year.
• Long-Term Semen Cryopreservation: Proven, time-tested
techniques enable semen specimens and embryos to be frozen and
stored indefinitely in liquid nitrogen.
Advantages of frozen sperm
No risk of STD and AIDS as the
samples are quarantined for three
months and the donors are retested.
A round the clock availability; no
scheduling bottle neck.
High quality product since it is
tested before and after freezing
Rh negative donors can be used for
Rh negative women
Physical traits of husband and
donor can be matched
Disadvantages of fresh semen
There are no records of the
donors.
It's impossible to match the
physical traits of the donor and
the husband.
Using known donors can lead to
legal , emotional and ego
problems.
The quality of the sample is
always suspect.
It could be difficult to produce a
donor at the critical time and
occasionally a treatment cycle
has to run dry.
• Donor sperm prepared for use by ;
Assisted reproductive technique
1. Artificial insemination :
a) intra uterine insemination(IUI),
b) intra-cervical insemination(ICI),
c) IVF,
d)ICSI,
2.Natural insemination:
SURRVOGACY
Type of artificial insemination
Artificial insemination homologous(AIH): semen of husband is
used,
Artificial insemination donor(AID): semen from a person other
than husband,
Artificial insemination homologues donor(AIHD): mixture of
donor semen and husband semen is used,
Surrogacy
“Surrogacy”, means an arrangement in which a woman
agrees to accept and bear pregnancy either by AI or by the
way of implantation of in-vitro fertilized embryo, with the
intention to carry it to term and handover the child to the
person or persons for whom she is acting as a surrogate.
Traditional surrogacy (Traditional/ Straight): when surrogate
mother is the baby's biological mother.
Gestational surrogacy: when surrogate mother is implanted
with someone else fertilized egg. she accepts pregnancy either by
AI or by implantation of in-vitro fertilized ova at the blasto-cyst
stage. Not genetically/biologically related to the child.
Commercial Surrogacy:
• in which a gestational carrier is paid to carry a child to maturity in
her womb.
• is usually resorted to by higher income infertile couples who can
afford the cost.
• This procedure is legal in several countries including India.
• Commercial surrogacy is also known as ‘wombs for rent’, outsourced
pregnancies’ or ‘baby farms’.
Altruistic Surrogacy :
• Altruistic surrogacy is a situation where the surrogate receives no
financial reward for her pregnancy or the relinquishment of the child.
• But all expenses related to the pregnancy and birth are paid by the
intended parents such as medical expenses, maternity clothing,
accommodation, diet and other related expenses).

ICMR guidelines on Surrogacy
1. A child born through surrogacy must be adopted by the biological
parents unless they can establish through DNA fingerprinting.
2. Surrogacy by ART allowed only for patients , physically or medically
impossible to carry a baby to term.
3. Payments to surrogate mothers should cover all genuine expenses
associated with the pregnancy.
Documentary evidence of the financial arrangement for surrogacy must be
available.
The ART centre should not be involved in this monetary aspect.
4. Advertisements regarding surrogacy should not be made by the ART
clinic.
5. A surrogate should not be over 45 years of age.
6 . A relative, a known person , as well as a person unknown to the couple
may act as a surrogate mother for the couple.
7 . A surrogate mother must be tested for HIV and shown to be sero-
negative just before embryo transfer. provide a written certificate that ;
(a) h/o iv drugs use.
(b) not undergone blood transfusion.
(c) she and her husband (to the best of her/his knowledge) has
had no extramarital relationship in the last six months.
8. No woman may act as a surrogate more then thrice in her lifetime.
Present Indian scenario
1. Litigation against doctors :doctors can face few litigations like-
a. Not taking proper informed consent: After duly counselling the couple
/semen donor, an informed and written consent should be taken from both
spouses as well as donor.
b. Following the birth of a defective child: To avoid this, the donor's
chromosomes must be thoroughly screened for possible genetic defect.
2. Legitimacy - The child born by ART is considered legitimate with all the
rights of parentage, support and inheritance, provided he is born during
lawful consent of both the spouses.
A child can be given status of legitimacy also by adoption.
In a case, on the wife's petition for divorce and custody of the child,
• Child belong to mother alone.
• Husband had no rights or interest in the child.
• Child is illegitimate.
3. Inheritance of property:
• Child is illegitimate, if born out of AID.
• It cannot inherit the property of his father.
• Any attempt to conceal this fact by registering the husband, as the father
amounts to perjury.
4. Consummation of marriage:
• Conception of the wife by AI (AIH or AID) does not amount to
consummation of marriage.
• If no successful sexual act due to the impotency of husband.
• The decree of nullity may still be granted in favour of the wife or his wilful
refusal to consummate the marriage.
• The child will be illegitimate.
5. Rights of an unmarried woman to AID:
• There is no legal bar on an unmarried woman going for AID.
• A child born to a single woman through AID would be deemed to be
legitimate.
6. Ground for divorce and judicial separation:
• AI is not a ground for nullity of marriage and divorce since sterility is not a
ground.
• If AI is due to impotence of husband, it becomes the ground.
• AID without husbands consent can be a ground for divorce and judicial
separation.
7. Maintenance and custody of child: Under Hindu Adoption and
Maintenance Act 1956 the maintenance of the dependents is the
responsibility of the parents, whether legitimate or illegitimate, till the son
remains minor and daughter is unmarried.
8. Insemination after the death of the husband:
• When semen of the husband is cryo-preserved by various methods and the
women is inseminated after death of the husband.
• Posthumous child is said to be legitimate because the semen is of husband.
• Complexity arises since conception is not during the continuance of marriage.
9. Relation between AIH / AID child with subsequent Natural / Adopted
child of same family:
• If the child is born of natural course after the birth of the child through AI.
• The status will remain same for AI child but the natural child born will
remain legitimate.
10. Charge of Adultery:
• AID does not amount to adultery, even if done without the consent of
husband.
• For adultery to be committed both parties should be physically present and
engage in sexual act.
• AI not equivalent to sexual intercourse.
• For the charge of adultery to be proven,
sexual intercourse took place with another person's wife.
No consent or connivance from another man was granted.
11. Incestuous relationship: There is high risk of such relationship between
naturally born child and child born out of AID of the same parent.
Challenging Ethical Issues
A. Individual moral constraints on trying for reproduction “at any cost.
• Sex selection,
• screening for defect,
• Selective abortion ,
• Surrogate motherhood,
• Cloning,
B. Baby factory sells newborns like in Warsaw , Poland of Rs 11,000. It is
home to 37 young surrogate mothers. They say, they are offering services
since 1.5 million couple in Poland are being childless and they need more
peoples.
C. Posthumous Artificial insemination :due to availability of
semen banking, problems in inheritance rights of a child, born
after the death of genetic father.
D. Dehumanizing aspects of procedures : Moral status of the
Left-over Embryos, Egg, Sperm, and the Fertilized Egg stored
for a married woman who subsequently died.
E .Japanese surrogate baby Manjhi case :in a gestational
carrier was paid to carry the child to maturity in her womb and
was usually resorted to by couples to complete their dream of
being parents.
German couple: is striving hard for the citizenship of their twin
surrogate baby, born in India
F .An Israeli gay couple categorical has dislike for Section
377 of the Indian law that makes homosexuality a criminal
offence, but they like the `desi' regulation that allowed them to
hire a surrogate mother to deliver their child here. " Israel
doesn't allow same-sex couples to adopt or have a surrogate
mother.
First Gay couple to have a baby thru surrogate in
India
• Homosexual ManLesbians Single Partner
Right to have babies ???Bearing or Rearing ???Legal & Moral Status ???Production or Reproduction ???
Changing Society – Changing Concept
Why Surrogacy in India?
Indian surrogates very popular b/o-
• Easy availability
• Low cost
• Non demanding
• Indian clinics are becoming more
competitive
in pricing and retention and hiring of
surrogates.
