Mani (seminal fluid) 3 jagha banta hai:

1. Testis
2. Prostate Glands
3. Seminal Vesicles

    Inn teeno jagha sey nikal kar peeshab ki nali mein jama hojata hai. Testis mein 2 types ka cells hotain hain. Aik kisim jinsi hormones testosterone paeda kartey hain jinka ta'alluq sexual drives aur mardana potency yani tanau (erection) ka sath hai. Yani es hormone ki wajha sey shawat aur penis mein tanau (erection) paeda hoti hai. Doosrey cell sperms paeda kartey hain jo bachai paeda karna ka sabab bantai hain. Insan jab aik bar ejaculate kar daita hai to kharij hona wali mani (seminal fluid) ki ta'adad 3.5ml hoti hai jismai 20 crore sey 1 million sperms hotey hain. Pregnancy ka liye 3 crore active sperms ki zarorat hai magar es surat mein usually larki paeda hoti hai. Agar sperms zyada hongai to larka paeda hona ka chances mein ezafa hojata hai. Sperm ka jinsi quwwat ka sath koi ta'alluq nahi. Agar sperms bilkul khatam bhi hojain to bhi insan ki mardana quwwat per koi asar nahi parta aur woh jinsi amal ka liye bilkul fit hota hai. Essi liye baaz afrat jinsi lihaz sey bohut mazboot aur active hotey hain magar woh bacha paeda nahi kar saktey hain. (Kothari:Shettle)
