Descrizione dettagliata
Prospective, multicenter, single-arm, open label, interventional clinical trial investigating the safety and effectiveness of the Plan A Male Contraceptive System to occlude the vas deferens to block the passage of sperm and then be reversed to subsequently allow the passage of sperm through the vas deferens. 40 men (all sites) will be enrolled and treated with Plan A occlusion (Vasalgel®) using DLAD (Delivery Lumen Access Device). The study will enroll into two groups. Group 1 will include 30 subjects that will be followed for up for a maximum of 6 months post occlusion procedure, or until they achieve azoospermia at which point they will be offered a vasectomy procedure. Group 2 will recruit ten subjects who will be followed for up for a maximum of 6 months post occlusion procedure, or until they achieve azoospermia at which point they will have the reversal procedure using the Plan A RD (Reversal Device). This group will be followed for up to another 3 months maximum, or until baseline semen levels are achieved at which point they will be offered a vasectomy procedure. Ten men reaching azoospermia after their occlusion procedure will be allocated to Group 2 and will go on to have the reversal procedure.

- 25 to 65 years of age at the time of consent
- Body Mass Index (BMI) <31 kg/m2
- Good health for undergoing a vasectomy as confirmed by medical history, physical examination and clinical laboratory tests of blood and urine at the time of screening
- Normal semen analysis defined by the WHO Laboratory Manual for the Examination and Processing of Human Semen (6th Edition), based on the average of two semen samples ≥2 days and ≤7 days apart
- In the opinion of the Investigator, subject is suitable to undergo a vasectomy as a form of long-term contraception
- Agreement to use an effective method of contraception during the entire clinical trial until the planned vasectomy
- Lives in close proximity to the trial site to enable provision of fresh semen samples unless the subject agrees to provide semen samples at the trial site or laboratory
Exclusion Criteria:
- (On exam, has any of the following); one or both vasa not present, abnormal scrotum, large varicocele, hydrocele, filariasis or elephantiasis of scrotum, or intrascrotal mass that would make the subject not suitable for the study.
- Prior testicular surgery, testicular injury or prior vasectomy with vasovasostomy (vasectomy reversal)
- Recurrent pain with ejaculations
- Has known allergic reaction to sulfur-containing products or has had a prior severe allergic response to injectable or implantable devices
- Has local genital infections such as balanitis, scrotal skin infection, epididymitis, or orchitis, or tender (inflamed) tip of the penis, but may be enrolled after resolution of an acute infection
- History of prostatitis or benign prostatic hypertrophy requiring treatment
- Has undergone prior chemotherapy
- Has known current coagulopathy or other bleeding disorders
