of endometrial cells in the uterus, which develop under the influence of the hormone 'Estrogen'. Ovulation is the rupture of a follicle with the release of a mature ovum into the Fallopian tube. It usually occurs on day 14 or 15 of the cycle. The postovulatory (premenstrual) phase is the time between ovulation and the onset of the menstrual bleeding and normally lasts 14 days. During this phase the ovum travels through the Fallopian tube to the uterus. If the ovum becomes fertilized during this passage, it will become implanted in and nurtured by the newly developed endometrial lining. This infact is the proper “Garbha Dhána Muhürta” or the placement of the moment of the conception, which may be 24 - 48 hours after the day of ovulation. However, if fertilization does not take place, the lining deteriorates and eventually sloughs off, marking day 1 of the next cycle. This in a nutshell are the organs and their fitness in the female.

1.2.2 Male Reproductive System

The primary sex organs of the male are the Testes, which produce sperm cells (spermatozoa) and the hormones involved for reproduction.

Structure of Testis

The testes are two oval glands suspended inside a sac, the 'scrotum' by spermatic cords. This cord is formed by the Vas Deferens, its arteries and veins, as well as lymphatics, and nerves - all bound together by connective tissue.

Each testis is encapsulated by a tough, white, fibrous tissue called the tunica albuginea. The interior of the testis is divided into 250 lobules (small lobes). Each lobule contains 1 to 4 highly coiled, convoluted tubules called Seminiferous tubules. These
