4. Reproductive Consequences of ROS
and Oxidative Stress
In-Vitro Fertilization (IVF) / Intracytoplasmic
Sperm Injection (ICSI) Outcomes:
• ICSI is also affected for an excessive presence of
ROS molecules in seminal plasma and sperm.
• The damaged cell development generated by
oxidative stress, causing apoptosis and embryo
fragmentation.
5. Antioxidants
Astaxanthin several-fold stronger antioxidant activity than vitamin E and b-carotene.
potent antiperoxidation activity.
Coenzyme Q10 Protects the cell membrane from lipid peroxidation.
improves Total Antioxidant Capacity (TAC) concentrations and decreased
Malondialdehyde (MDA) levels.
L-Carnitine increases fatty acid transport into sperm mitochondria which are needed for sperm
energy production.
Lycopene antiproliferative, immunomodulatory, and anti-inflammatory effects that promote cell
differentiation .
Vitamin B9 (Folic
Acid)
Protects against mutations and DNA strand breaks.
Regulates DNA methylation and gene expression
prevents abnormal chromosomal replication and mitochondrial DNA deletions.
Zinc role in signaling, enzymatic activities, sexual maturation and managing mitochondrial
oxidative stress.
improves chromatin integrity
Selenium Suppresses testicular toxicity and modulate DNA repair.
6. Combined conventional/antioxidant "Astaxanthin"
treatment for male infertility: a double blind,
randomized trial
• Astaxanthin 16 mg/day or placebo for 3 months were given
Results:
• ROS and Inhibin B decreased significantly.
• Sperm linear velocity increased in the Astaxanthin group.
• The results of the zona-free hamster oocyte test* tended to improve in the
Astaxanthin group.
• A total pregnancy rate of 54.5 % in the Astaxanthin group.
• The conception per month was 23.1 % in the Astaxanthin group.
• .
Asian J Androl 2005; 7 (3): 257–262
Conclusion:
The present study suggests a positive effect of Astaxanthin on sperm parameters and fertility.
7. Coenzyme Q10 supplementation in infertile men with low-
grade varicocele: an open, uncontrolled pilot study
• To evaluate the antioxidant capacity of seminal plasma of infertile
men with varicocele.
• 38 patients were recruited.
• Patients underwent an oral supplementation with CoQ10 at a dosage
of 50 mg twice a day for 12 weeks.
• A semen analysis was performed at baseline and 3 months.
• Coenzyme Q10 therapy improved semen parameters and
antioxidant status.
Andrologia. 2014 Sep;46(7):805-7
8. The effect of L-Arginine of treatment for infertile men on
semen parameters
• L-arginine was given orally at a dose 1000 mg one capsule per day morning.
L-arginine which provides protection against oxidative stress.
It protects spermatozoa against lipid peroxidation by increased the release of
nitric oxide gas.
Supplement of arginine per day to infertile men markedly increased sperm count
and motility.
Significant elevation in the concentration of Glutathione (GSH). A significant
reductions in the concentration of Malondialdehyde (MDA), Interleukin 6 (IL-6),
and C- Reactive protein (CRP).
Tikrit Journal of Pure Science Vol. 24 (5) 2019, 1-4.
Significant reduction in Sluggish, abnormal sperm shape and non-motile sperm
count after treatment with L-Arginine.
9. • 60 patients were included with 30 patients in
case and 30 patients in control groups.
• Homocysteine lowering agents were given (folic
acid 5mg, vitamin B12 500 microgram, vitamin
B6 5 mg )
• Homocysteine lowering agents were given for 6
weeks.
• Re-assessed homocysteine levels after 6 weeks.
• Outcome:
Conceptions over a period of one year were
also noted.
• Results:
homocysteine levels was 10.4 µmol/l
Int J Reprod Contracept Obstet Gynecol. 2013 Jun;2(2):165-171
To study the role of hyperhomocysteinemia in
unexplained infertility
Conclusions:
Homocysteine lowering agents
have a favourable impact on the
outcomes.
Their use is suggested in cases of
infertility associated with
hyperhomocysteinemia.
12. 1. Men’s fertility potential depends
on female factors
• Assessment of tests and treatments for the male is
challenging due to inconsistent endpoints and the
observation that many of these endpoints are
dependent upon and measured from the female
partner.
• Ideally, the endpoint for fertility trials should be "live
birth or cumulative live birth (WHO, 2021)
17. Limitations of WHO Guideline
• 5 percentile and time-to-pregnancy (TTP) concept
• Not true reference values but recommends
acceptable levels.
• Day to day variation
18. Sperm DNA
Fragmentation (SDF)
Infertile men with:
• Repeated IUI or IVF failure
• Recurrent spontaneous
miscarriages (ESHRE, 2018)
• Previous low fertilization,
cleavage or blastulation rate
• Varicocele with
normozoospermia
• Advanced male age (>40 y)
Significance of SDF
• Live birth after IUI/ IVF/
ICSI- ?
• Oocytes can repair the
damaged DNA
• Lack of standardization
• Lack of definitive treatment
Is “Routine” Semen Analysis ENOUGH?

29. What next?
• Straightaway donor sperm IUI
• Antioxidants for 3 months and repeat test
• Investigate in details√
• History
• Physical Examination
• Hormone Assay
• Imaging
• Genetic Tests
30. Severe Male Factor is NOT ONLY a fertility
problem
• Diabetes
• Cardiovascular diseases
• Lymphoma, extragonadal
germ cell tumours, peritoneal
cancers
• Repeated hospitalization
• Increased mortality
• Testicular Cancer
Choy and Eisenberg, 2020; Bungum et
al., 2018; Eisenberg et al., 2013;
Jungwirth et al., 2018; Hotaling and
Walsh, 2009
Self-Testicular
Examination
•Atrophic Testes
•H/O undescended testicles
•Testicular microcalcification
(post-mumps or others)
31. Sperm abnormality may be the first
symptom of testicular cancer
• 31 yrs
• Came for IUI (D)
• Malignant teratoma-
treated by orchidectomy
and chemotherapy
32. Severe Male Factor- if not left
untreated ???
• Overall, 16 (24.6%) of 65
patients with severe
oligozoospermia developed
azoospermia.
• Two (3.1%)patients with
moderate oligozoospermia
developed azoospermia
• None of the patients with
mild oligozoospermia
developed azoospermia.
33. Revisiting History
• Age
• Duration of subfertility
• Previous pregnancy- can have secondary male
subfertility
• Lifestyle
• Occupation- Driving, IT, chemical industry (heavy
metal, pesticides)
• Medical history- Diabetes, Mumps, Cancer
• Surgical history- Hernia, Orchidopexy, Pituitary
Surgery, Bladder neck surgery
• Drug history- Sulphasalazine, Finesteride,
cytotoxic drugs, steroids
• Sexual history- Low libido, ED
34. Darren et al. Male infertility – The other side of the equation . 2017
35. Varicocele- always CLINICAL Diagnosis (EUA,
2018)
• Subclinical: not palpable or
visible, but can be shown by
special tests (Doppler
ultrasound).
• Grade 1: palpable during
Valsava manoeuvre, but not
otherwise.
• Grade 2: palpable at rest, but
not visible.
• Grade 3: visible at rest
36. Surgery for Varicocele
(EUA, 2018)
• Grade 3 varicocele
• Ipsilateral testicular atrophy
• Pain
• Abnormal semen parameters
• No other fertility factors in the couple
37. In couples seeking fertility with ART, varicocele repair
• may offer improvement in semen parameters
• may decrease level of ART needed
38. • 14 studies (980 individuals) in the systematic review.
• Contradictory findings were reported in sperm
concentration, morphology, and motility, as well as
DNA fragmentation.
• Most included studies also raised methodological
concerns.
• Therefore, definitive conclusions about the efficacy of
antioxidant supplementation in this setting cannot be
drawn
Antioxidants in Varicocele
39. Cryptorchidism in adults (EUA, 2018)
• In adulthood, a palpable undescended
testis should NOT be removed because it
still produces testosterone.
• Correction of B/L cryptorchidism, even in
adulthood, can lead to sperm production in
previously azoospermic men
• Perform testicular biopsy at the time of
orchidopexy in adult- to detect germ cell
neoplasia in situ
40. Cryptorchidism- bilateral in adults?
• 31 yr
• Azoospermia
• USG- Rt testis in lower abdomen, Lt testis in inguinal canal
• FSH 13.40. LH 6.87. Testo 6.89. E2 <10.

48. Role Of Medical Therapy
(EUA, 2018, ASRM, 2020)
Hypogonadotropic
hypodonadism
•hCG 2000-5000 IU 3 times a week
•If hCG alone cannot restore spermatogenesis, FSH is
added 75-150 IU 3 times a week
•Serum testosterone and semen analysis every 1–2 months
•Usual time to recover 6 – 12 months (may take 24
months)
•Natural conception vs ART?

• may improve live birth rates
• clinical pregnancy rates may also increase.
• Overall, there is no evidence of increased risk of
miscarriage, however antioxidants may give more
mild gastrointestinal upsets
• Subfertilte couples should be advised that overall, the
current evidence is inconclusive.
52. • In some studies, AS was found to be beneficial in
reversing OS-related sperm dysfunction and improving
pregnancy rates.
• The most commonly used preparations, either as
monotherapy or in combination as multi-AS, were: vitamin
E (400 mg), carnitines (500–1000 mg), vitamin C (500–
1000 mg), CoQ10 (100–300 mg), NAC (600 mg), zinc (25–
400 mg), folic acid (0.5 mg), selenium (200 mg), and
lycopene (6–8 mg).
• Still debatable due to the heterogeneity in study designs
and the multifactorial genesis of infertility.

ASRM, 2020; Vignera et al., J Med Microbiology, 2014
• The clinical significance is controversial.
• Special Tests- Round cells vs Pus cells
• Method of collection
• Hand washing before collection
• Culture of semen
• Antibiotics- only when documented infections
• Consider prostatic fluid culture
91. A story of “Pus cells”
• 36-yr
• Apparently
unexplained infertility
• Persistent Pus cells in
semen
• Culture negative
• Pain during
intercourse
• Paraphimosis
• No pus cells after
circumcision
• Conceived after OI,
delivered
95. 1. Meticulous semen analysis in a standard laboratory
2. Physical examination and rational investigations
3. Avoid non-evidence based drugs for long time
4. Antioxidants- May be useful in mild problem
5. Antioxidants- Not reliable in severe problem
6. Donor sperm is NOT the only solution
7. IUI or IVF/ICSI- depends on the overall assessment
