Seminal plasma in human males is rich in _________.
The external genitalia of human female is called as _________.
The external genitalia are accessory structures of female reproductive system that are external to vagina they are also referred as vulva or pudendum the external genitalia includes the labia majora, mons pubis, labia minora, clitoris and glands within vestibules.
The primary sex organ of human male is _________.
Testis is the primary sex organ in human male as it produce sperm or male gametes without which reproduction is not possible.
Male Reproductive System:
The endometrium in female is the lining of _________.
The innermost lining of the uterus is called the endometrium. It is the spongy layer that breakdown during the menstrual cycle along with mucus through the vagina.

The number of polar bodies formed during oogenesis in human being is:
Three polar bodies.
First one is produced when a mature primary oocyte transforms into a secondary oocyte. The first polar body divides again to produce two more polar bodies. When the secondary oocyte transforms into an ovum (mature), a polar body is generated. Hence, three polar bodies are produced during oogenesis.
Oogenesis is the process of the formation of female gametes. It is a type of gametogenesis taking place in the female reproductive system. Here, the female gamete or ova are formed. This female gamete comes to be known as the ovum. Oogenesis involves three stages – pre-natal stage, antral stage, and Pre-Ovulatory Stage.
Once fertilization occurs, meiosis-II is said to be completed. This gives away the third polar body. In the event that fertilization does not take place, oocytes degenerate 24 hours post the ovulation while it is still arrested in the meiosis-II cell division.
In oocyte secondary maturation occurs in _________.
Beginning of menstrual cycle is called as _________.
Which of the following hormone is produced in female only during pregnancy?
Relaxin is produced by corpus luteum and is responsible for the inhibition of uterine contraction. It also helps in dilation of the cervix. This hormone is produced only during pregnancy.
The _________ is the sexual intercourse between male and female sex.
Transfer of male gametes (sperm) into female genital tract occurs during sexual intercourse that may leads to fertilisation of ovum for pregnancy. Sexual intercourse is called as coition or coitus.
Ovulation occurs on the _________ day of menstrual cycle.
The release of ovum from ovary during menstrual cycle is is called ovulation. Ovulation occurs in the middle of menstrual cycle that is on 14-16th day of start of menstrual cycle.
The cellular layer that disintegrates and regenerates again and again is _______.
Endometrium is the inner lining of uterus which disintegrates and regenerates again and again during menstrual cycle.
During which month of pregnancy first movement of fetus is observed?
How does human sperm locomote?
The tail of the sperm, the flagellum, is what gives sperm motility.
Acrosome is filled with _________.
