Estrogens - An excess of sex steroids, either estrogens or androgens, can cause male infertility due to an imbalance in the testosterone-estrogen ratio. E.g Hepatic cirrhosis, adrenocortical tumour. 2.Androgens - An excess of androgens can suppress pituitary gonadotropin secretion and lead to secondary testis failure. The use of exogenous androgenic steroids (anabolic steroids) result in temporary sterility due to this effect. 3. Glucocorticoids - Exposure to excess glucocorticoids either endogenously or exogenously can result in decreased spermatogenesis. Elevated plasma cortisone levels depress LH secretion and induce secondary testis failure. 4. Hyper- and hypothyroidism - Abnormally high or low levels of serum thyroid hormone affect spermatogenesis Thyroid abnormalities are a rare cause (0.5%) of male infertility. 5. Growth hormone - Some infertile men have deficient responses to growth hormone challenge tests and may respond to growth hormone treatment with improvements in semen quality
Transcript of "Infertility"
A 33 years old Omani lady k/o primary infertility was present to the A&E with referral
from private clinic .
She presented with sever lower abdominal pain from 3 days which get worse
with time. It was colicky in nature, not radiating, and she can’t tolerated
with it. There was history of abdominal distention, SOB, vomiting and
4 days before pt. underwent Intra cytoplasmic sperm injection (ICSI)

such as anosmia, cleft lip and cleft palate, deafness,
cryptorchidism, and color blindness.

there is insufficient FSH production by the pituitary. Patients are
normally virilized, as LH is present. FSH levels are low. Sperm
counts range from azoospermia to severely low numbers

– Causes of Male infertility - Testis Injury
– Inflammation of testis tissue is most commonly due to bacterial
infection, termed epididymo-orchitis.
Testicular TorsionTesticular Torsion :
Ischemic injury to the testis secondary to twisting of the testis on the
spermatic cord. Torsion may result in inoculation of the immune
system with testis antigens that may predispose to later
Can invoke an abnormal immune response in addition to atrophy
resulting from injury. Both may contribute to infertility.
–Causes of Male infertility - Cryptorchidism
–Males with either unilaterally or bilaterally undescended testes are at
risk for infertility later in life. Prophylactic orchidopexy is generally
performed by 2 years of age
–A varicocele is defined as dilated and tortuous veins within the
pampiniform plexus of scrotal veins.
–Increased intratesticular temperature, reflux of toxic metabolites
–at least 25%-50% of male infertility has no identifiable cause

–Antibodies disturb sperm transport or normal sperm-egg interaction.
–Antibodies may cause agglutination of sperm, which inhibits passage,
– or may block normal sperm binding to the oocyte
–Disorders of Coitus - Causes of Male infertility
B. Sexual issues.
– Often treatable, problems with sexual intercourse Difficulties with
erection of the penis (erectile dysfunction), premature ejaculation,
painful intercourse (dyspareunia), or psychological or relationship
problems can contribute to infertility. Use of lubricants such as oils or
petroleum jelly can be toxic to sperm and impair fertility.
May not place the semen at the cervical os.
–D. Timing and Frequency
Simple problems of coital timing and frequency can be corrected by a review of
the couple’s sexual habits. An appropriate frequency of intercourse is every 2
days, performed within the periovulatory period.

Management of unexplained infertilityManagement of unexplained infertility
The most efficient management is clomiphene citrate and
performance of intrauterine insemination (IUI).
If this has not resulted in pregnancy, it appears most useful to
subsequently perform in vitro fertilization (IVF).
The administration of clomiphene citrate is intended to achieve
ovulation induction or ovarian hyperstimulation.
Human chorionic gonadotropin (hCG) is given to trigger
ovulation, and the intrauterine insemination is performed within 2
days of hCG administration.
