It is often questioned whether sperm parameters, including whether retrieved or ejaculated, have any effect on intracytoplasmic sperm injection (ICSI) results. Do severe spermatogenic defects affect embryo quality or pregnancy rate? Further, does it matter in azoospermic patients whether the sperm source is testicular or epididymal? Our studies show there is no significant difference in results...

OBJECTIVE To examine the relationship among sperm apoptosis, sperm chromatin status, and DNA ploidy in different sperm fractions. DESIGN Prospective study. SETTING Reproductive research center in a tertiary care hospital. INTERVENTION(S) Sperm prepared by density gradient were evaluated for sperm count, motility, apoptosis, and sperm chromatin assessment. MAIN OUTCOME MEASURE(S) Sperm c...

In the present study, the effect of four Vajikaran Rasayana herbs on penile erection, sperm count, seminal fructose content in vivo and nitric oxide (NO) release in vitro was assessed. Lyophilised aqueous extracts of Asparagus racemosus Willd. (AR), Chlorophytum borivilianum Sant. F. (CB), Curculigo orchioides Gaertn. (CO), and Dactylorhiza hatagirea (D. Don) Soo (DH) were orally administered a...

Objective: To study the effects of Mesterolone alone and combination of Mesterolone and Clomiphene Citrate on semen parameters, pituitary axis and liver function in Idiopathic Oligospermic males. Materials and Methods: 30 males with Idiopathic Oligospermia (sperm count < 20-million/ml) between 20-45 years of age were included in the study. Of the 30 subjects, 10 were given tab Mesterolene 50 mg...

Semen analysis of 66 unmarried medical students in the age group of 17-21 years was carried out. A higher liquefaction time pH, motility, lower sperm count and abnormal forms were observed compared to reported values. Liquefaction time, pH and sperm count was found significantly different in non-vegetarians and vegetarians, perhaps due to difference in their dietary proteins.

The semen samples of 1,110 (one thousand, one hundred and ten) Igbo males attending infertility clinic, aged between 30-50 years were collected and analyzed. The specimens were collected and analysed in the microbiology laboratory of the University of Nigeria Teaching Hospital (UNTH) Enugu, Eastern Nigeria.

The effect of aqueous leaf extract of Azadirachta indica (Neem) on reproduction was studied on male albino rats. The study was divided into three groups of six animals each. The first group (I) received distilled water serve as control. The second and third groups (II and III) of animals were administered the aqueous leaf extract daily at 250mg/kg body wt., and 350mg/kg body wt., respectively f...

BACKGROUND Although the effect of maternal age on fertility is well known, it is unclear whether paternal age also affects fertility. This cross-sectional study sought to characterize the association between age and semen quality, a well-known proxy of fertility status. METHODS A convenience sample of 97 non-smoking men (aged 22-80 years) without known fertility problems was recruited from a ...

BACKGROUND Nicotine consumption can decrease fertility drive in males by inducing oxidative stress and DNA damage. Urtica dioica L (U.dioica) is a multipurpose herb in traditional medicine for which some anti-oxidative and anti-inflammatory properties have been identified. OBJECTIVE The main goal is to investigate whether the U.dioica could inhibit nicotine adverse effects on sperm cells viab...

Cisplatin (CIS) is used in the treatment of cancer, but its nonspecific systemic actions lead to toxic effects on other parts of the body. This study investigated the severity of CIS toxicity by increasing its dose over a constant time period. Sprague Dawley rats were divided into five treatment groups and control group with CIS (2, 4, 6, 8, and 10 mg/kg) administered intraperitoneally for 5 da...
