Summary Objective: Sperm cryopreservation before gonadotoxic treatment is the basic and mos teffective method of preserving reproduction, which can be used during adolescence. The communication summarizes 26 years of experience in the operation of an oncological sperm bank, analyzes spermiograms of oncological patients, assesses the relationship between sperm pathology and diagnosis, and determines the number of deaths and the use of frozen sperm. Methods: During the existence of CAR 01 (assisted reproduction center), more than 50,000 spermiograms were performed. From January 1995 to December 2020, a total of 24,729 men were examined within the sperm bank, of which 1,448 (5.9%) had an oncological diagnosis. The spermiograms were evaluated according to current WHO (World Health Organization) manuals. Cryopreservation of sperm has undergone a major development. The rules for the storage of frozen cells have been laid down by Act No. 296/2008 Coll. since 2008. In 2019, the methodology „Cryopreservation of reproductive cells and tissues in patients before cancer treatment“ was updated. In all cases, the standard thawing technique was used. The sperms were processed by the swim-up method. As part of the treatment with assisted reproduction methods, oocytes were fertilized by the ICSI (intracytoplasmatic sperm injection) micromanipulation technique. Results: Out of 1,448 examined spermiograms in men with oncological diagnoses, testicular cancer was present in 43.7% of patients and malignant diseases of lymphatic and hematopoietic tissue were found in 24.1%, of which 70,1% included Hodgkin‘s lymphomas and 29,9% were non-Hodgkin‘s lymphomas. Leukemia was found in 7.9%, bone and cartilage cancers in 6.8%. The age of the clients of the whole group ranged from 13 to 64 years (27.2 ± 6.8 years). A total of 38.3% of men had normozoospermia, 54.2% of spermiograms showed pathological findings in 1 to 3 evaluated parameters and 7.5% of patients had azoospermia. Severe asthenozoospermia (mobility ≤ 10%) was detected in 57.2% of men and severe oligozoospermia (concentration ≤ 1 × 106 mm3) in 22.3% of patients. The lowest values of the spermiogram were found in men with testicular cancer; the best values were seen in CNS (central nervous system) cancers. The cryopreservation of sperm was performed in 1,340 cases (92.5%). So far, a total of 160 men (11.9%) have used frozen sperm, of which 6.2% in our center. In these 83 cases, the ICSI technique was always used, 38 clinical pregnancies (45.8%) and 32 births were achieved. We have registered 424 completed storages of semen (31.6%), of which 148 (11.0% of all oncology patients) were made due to death and the others at patients’ request. Using the sperm of the dead is a specific issue. Conclusion: In cancer patients, sperm pathologies occur in high percentage. The lowest spermiogram values were found in men with testicular cancer. It is necessary to take into account long-term storage and fertilization by micromanipulation methods. The number of men who die is significantly higher than the number of those who use sperm to treat infertility. Cryopreservation of sperm should be offered to each patient prior to the therapy leading to the destruction of spermatogenesis.

This study evaluated the effects of varying levels of Baobab seed-meal (BSM) on spermiogram of Shika Brown® breeder cocks. Thirty apparently healthy cocks aged 30 weeks with average body weight of 1.78 ± 0.03 kg were used for this study. They were acclimatized and randomly divided into three groups of 10 each. Group A (control), fed 0% BSM growers diet, groups B, (5%) and group C, (10%) BSM diets. Semen samples were collected from each cock twice weekly for 28 days and spermiogram evaluated. Results indicated significant (P< 0.05) difference for mean volume, percentage live spermatozoa, sperm gross motilities and concentration between the treatment groups (B and C) and the control group (A). Mean abnormal sperm of cocks in groups B and C were significantly (P<0.05) lower compared to group A. It was concluded that BSM is likely to improve semen characteristics in breeder cocks. Therefore, it is recommended that BSM at 5% and 10% is safe and should be incorporated into breeder cocks diet by farmers for enhanced semen characteristics. Keywords: Baobab, Shika Brown®, spermiogram, semen, breeder

This study was designed to evaluate the effects of melatonin and Allium sativum (garlic) on dibutyl phthalate (DBP) influence on spermiogram of rabbit bucks. Forty two (42) rabbit bucks were used for this study, bucks were randomly divided into 7 groups of 6 bucks each. Group A was administered olive oil for 16 weeks, group B (olive oil + DBP for 16 weeks), group C (melatonin for 8 weeks, then olive oil + DBP for another 8 weeks), group D (garlic for 8 weeks, then olive oil + DBP for another 8 weeks), group E (olive oil + DBP for 8 weeks, then melatonin for another 8 week), group F (olive oil + DBP for 8 weeks, then garlic for another 8 weeks) and group G (olive oil + DBP for 8 weeks, then melatonin and garlic for another 8 weeks). The observation period lasted for 120 days, during which semen samples were collected weekly between the hours of 8.00 am to 10.00 am using artificial vagina (AV).There were significant differences (P<0.05) in mean reaction time, semen volume, sperm motility, sperm concentration, percentage live spermatozoa and percentage abnormal morphology between DBP exposed groups and treatment groups. Conclusion, DBP has adverse effects on spermiogram but administration of melatonin and garlic has promising protective effects than therapeutic effect on rabbit bucks. Key words: Melatonin; Allium sativum; Dibutyl phthalate; Spermiogram; Rabbit Bucks

Studies in echography have proved to be of extreme value in screening male infertility. During recent years proposals have been put forward for man screening programmes in association with spermiogram. The prostate gland is a fundamental organ in reproduction, occupying an important position with regard to the seminal canal and prostatic secretion is responsible for 30% of seminal plasma volume.

We analysed sodium (Na), copper (Cu) and selenium (Se) levels in human semen and glutathione peroxidase activity (GPx) in seminal plasma and examined their relationships with sperm quality. Semen samples were obtained from men (n = 168) undergoing routine infertility evaluation. The study design included two groups based on standard ejaculate parameters: Group I (n = 39) with normal ejaculates (normozoospermia) and Group II (n = 129) with a pathological spermiogram. Se concentration (but not Na or Cu) and GPx activity were significantly higher in normozoospermic males than in those with a pathological spermiogram and also in males with correct sperm motility and normal sperm morphology than in asthenozoospermic and teratozoospermic males. There were significant correlations between sperm motility, Se and GPx, between rapid progressive motility and Cu, between sperm motility and Na, between normal sperm morphology and Se and Cu and between sperm concentration and Cu and GPx. Significant correlations were found between Na and Cu, between Na and Se and between Cu and Se in human semen in relation to alcohol consumption and tobacco use. Na, Cu, Se and GPx are related to sperm characteristics and male fertility and their survey could improve male infertility diagnosis.

Masters of Science
It is well documented that cigarette smoking and nicotine exposure create widespread physiological disorders in humans and animals. The primary tobacco constituent that is responsible for the toxicological consequences associated with the effects of tobacco smoke is nicotine (Van Lancker 1977). After maternal nicotine exposure, the fetal gonads and lungs are the principle sites of nicotine damage (Szuts et al. 1978, Mosier & Jansons 1972). Whilst the fetal lung has received widespread attention in this regard (Maritz 1988), the testis has never been studied. Therefore, I have chosen to explore the effects of maternal nicotine exposure on the testis of male offspring by evaluating various aspects of the male reproductive tract. It is believed that, in adult male smokers (Rosenberg 1987, Handelsman et al. 1984) and sexually mature animals (Mattison 1982) that are exposed to nicotine, male fertility may be compromised. However, these studies provide conflicting data on single parameters. It was therefore my objective to identify the effect of nicotine exposure on the male reproductive tract and to establish possible sites through which these effects may be mediated in adult male rats. The influence of nicotine was then investigated in male offspring after maternal nicotine treatment (MNT), and in sexually mature adult males after direct adult nicotine treatment (ANT). In the former experiment (MNT), 7 day pregnant rats were exposed to Img nicotine/kg body weight/day. Therefore, these offspring were indirectly exposed to nicotine during fetal development and early neonatal development. After weaning the animals were divided into two groups. One group did not receive further treatment (withdrawn group), whilst the other group was continually treated till adulthood (nicotine group), after which both groups were sampled together with the control. In the latter experiment (ANT), the animals were treated daily for 3 weeks and were sampled as above (MNT animals). The fundamental parameter investigated in both experiments to assess reproductive status was sperm quality (motility and morphology). Thereafter, it was necessary to establish a possible site where the effects of nicotine would occur. Testicular growth, epididymal structure, and plasma testosterone content were measured as probable localities of nicotine's effect. The results signify that maternal nicotine exposure poses a greater threat to the male reproductive system than adult nicotine exposure. In the MNT experiment, progressive sperm motility of the nicotine and withdrawn groups were 1.7% and 3.4% respectively. The proportion of abnormal sperm was 72% in each of the above groups. The lower quality sperm that is evident after nicotine exposure implies that the fertilizing ability of the animals may be impaired during adulthood. The data on testicular growth indicates that nicotine exposure during early development results in slower testicular development until maturity. The epididymal lining of these animals also increased after nicotine exposure, indicating increased cellular activity. However, these results from testicular and epididymal studies are inconclusive and need further work. In the ANT experiment, progressive sperm motility of the nicotine group was 1.2%, whilst the proportion of abnormal sperm was 58%. No other parameter was affected after nicotine exposure to adult animals. From the above data it is evident that nicotine exposed animals were subject to greater nicotine damage after maternal nicotine exposure during early development. Moreover, within the maternal nicotine treated experiment, the withdrawal of nicotine after weaning did not appear to reverse the injurious effects of nicotine that were established during early development. These effects were evident since the nicotine and withdrawn groups showed similar levels of damage in all instances. The most profound effects after adult nicotine exposure and maternal nicotine exposure were on sperm quality. The probable site of sperm impairment appears to be via retarded testicular growth and possibly, structural status of the epididymis after maternal nicotine exposure. The results from adult nicotine exposure however, suggest that sperm cells may be directly affected by nicotine exposure. An epidemiological survey was included to validate the basic conclusions established in animal research when compared to clinical data from human patients. No statistically significant changes were observed in this study between the patient's spermiogram results versus his smoking habits, and, that of his mother. From the level of significance it was concluded that cigarette smoking does not appear to be a cause of impaired fertility in already infertile patients. However, the data does suggest that cigarette smoking may well be a precipitating agent in male infertility. Experimentally, nicotine exposure impairs the male reproductive system to some extent. The effects of which are irreversible after indirect exposure (MNT) during development and may begin with poor testicular development. The effects of adult nicotine exposure implies that nicotine exposure in mature animals (ANT) acts directly on sperm cells to incapacitate them. It is well advised that cigarette smoking should be curbed in pregnant women and in adult males to alleviate contributing effects to male infertility.

Impact of spermiogramme quality on in vitro fertilization Master's Thesis Author: Bc. Lukáš Gold Field of study: Specialist in laboratory methods Charle's university in Prague Faculty of Pharmacy in Hradec Králové Number of couples who have problems with becoming pregnant increasis every year. Sometimes, change of lifestyle or alleviation of life tempo can help but in other cases couples have to use centre of assisted reproduction service. In some cases is inferility caused by only one factor, in other cases are factors combinated. The aim of this work was evaluation of question, if the spermiogramme quality influences quality of artificial insemination. The secondary aim was to evaluate which technique of oocyte active insemination by injection (Intracytoplasmic sperm injection, ICSI or Intracytoplasmic morphologically - selected sperm injection IMSI) is more successful at fertilization in vitro. Datas and results were taken from 100 couples who underwent therapy using donated oocytes at Zentren Prof. Zech - Pilsen, s.r.o. clinic. Men who gave a fresh ejaculate in day of oocyte collection by ovarian puncture are included in this work. Donated oocytes were micromanipulatively impregnated by spemrs which were taken from ejaculate. Acording to the spermiogramme results men were divided into two...
