1. | In spermiogenesis, spermatids are formed, while in spermiation, spermatozoa are formed. |
2. | In spermiogenesis, spermatozoa are formed, while in spermiation, spermatids are formed. |

Several hormones like hCG, hPL, oestrogen, progesterone are produced by:
1. | ovary | 2. | placenta |
3. | fallopian tube | 4. | pituitary |
1. | LH and FSH triggers ovulation in ovary |
2. | LH and FSH decrease gradually during the follicular phase |
3. | LH triggers the secretion of androgens from the Leydig cells. |
4. | FSH stimulates the sertoli cells which help in spermiogenesis |
1. | the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the fallopian tube |
2. | the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the cervix |
3. | the sperms are transported into the cervix within 48 hrs of the release of the ovum in the uterus |
4. | the sperms are transported into the vagina just after the release of the ovum in the fallopian tube |
