The perception of Cannabis toxicity and safety in society, politics, and even scientific circles has changed dramatically in recent years. Consequently, a few questions have been raised regarding the effects of marijuana (Cannabis sativa) on the human body and psychic abilities in the short and long term. This study is undertaken in order to compare sperm cells quality before and after incubation with Cannabis (marijuana) extracts (THC- THC-COOH and CBD).

Semen samples were obtained from men (n=10) with age range between 20 to 35, regardless of their fertility status. Analyses of semen parameters (volume, sperm count, motility), were analyzed within 1 hour after collection, according to WHO criteria 2020. For accurate results, Computer Assisted Sperm Analysis (CASA) system was used to determine sperm parameters. Each sample was exposed to 1 mL; 10 µg/mL of THC, THC-COOH, and CBD dissolved in methanol. All samples were also exposed to 1 mL pure methanol as a control group to eliminate the potential effects of methanol on sperm cells. Several smears (10 µL) of each sample were taken in order to assess the functionality of sperm’s chromatin integrity by employing a chromomycin (CMA3 ) and DNA fragmentation (Acridine Orange) assays.

After treatment sperm cells with 10µL THC, THC-COOH and CBD. Total sperm’s motility was significantly reduced significantly when it was exposed to THC and CBD (P ≤ 0.001 and P ≤ 0.003 respectively). Progressive motility were decreased significantly (P ≤0.001) and the mean number of immotile sperm were significantly increased (P ≤ 0.003) after incubation with THC and CBD and respectively. However, slightly inhibition of total sperm’s motility was observed after incubation with THC-COOH.

Spermatozoa exposure to THC, CBD and THC-COOH deteriorate significantly sperm motility and should be avoided by men in reproductive age and those who undergoing ART.

Bile duct injury (BDI) is a severe and sometimes life-threatening complication of cholecystectomy. Several series have described a 0.5% to 0.6% incidence of BDI during laparoscopic cholecystectomy. We received an emergency call from the operating theater by the surgery team to assess an iatrogenic BDI in a 58-year-old man with cirrhosis who presented for laparoscopic cholecystectomy. After many trials by endoscopic retrograde cholangiopancreatography (ERCP) the guide wire passed to the peritoneal cavity and failed to pass proximally. Laparoscopy resumed, and the surgeon tried to pass the flexible guide wire proximally unsuccessfully. Then, a decision to hold the sphincterotome by laparoscopy and passing it proximally in harmony with ERCP was taken, which was successful. A regular ERCP with 10F plastic stent insertion was carried out, and the perforation was secured by the inserted stent without any further surgical intervention. Laparoscopy-assisted ERCP may give new insights into the immediate repair of iatrogenic bile duct injuries.
